Sorry Danny, I am not wasting money on high priced cables when the regular speaker wire I have sounds just fine. If I had the money, I would buy them for the looks, not the sound.
Absolutely. He puts 4 ohm resistor that is the equivalent of 4 THOUSAND feet 10 gauge wire. How is this relevant??? I think this channel might be trolling us for views.
exactly , how many turns of wire are in each coil, straight speaker wires will not behave the same, unless you leave all the wire on the large spool it came on except for a couple of feet on either end to connect to the amp and speaker, and then put both spools on top of each other.
12:05 "Have we learned anything yet?" Oh there is so much to unpack here. You pretend that people think cables don't matter. You claim that you know which cables sound better. You are using coils which are not remotely comparable to straight wires. Seriously, not even close. Your woven cable *still* just has a lot of parallel wires that *will* still induce on eachother. And ofcourse; you clai to be able to hear the interference of self-induction in a cable that is only running a few amps max. No, you cannot. Forget it. just forget it. Does your cable sound different? I'm sure it does! Does that have anything to do with the principles you tlked about? I seriously doubt it. Does it sound better? That is 100% up to you. Can you charge lots of money for your cables? Ofcourse! The are always people who know less about how low-frequency electricity works than you so you can always find people that you can convince with an irrelevant experiment on a youtube video. hell, I've had people offer me stickers to stick on the side of my speaker cabinets to make it sound better. Rocks to put on top of the transformer to "balance it out". And yes, they all claimed to know exactly how it worked and that it made things sound better. Don't talk about science if you're not going to show the science. Show that your cable makes an AUDIBLE difference in a double-blind test with a hundred people and have them all agree that your cable sounds better. THAT is science.
Actually, real science would be to perform a null test against other way cheaper cables of the same length, and when the sound cancels out and leaves only silence, understand that they won't make a difference to the sound
There is a guy on RU-vid who does a blind test and gets it right. Also, you admit cables do affect the sound. So to what do you ascribe the differences to?
Everything was fine until you started to talk about cables. No one is questioning mutual inductance between coils with many windings aligned in these different ways, but you cannot just infer from there.
Well, if you can infer that "seventies-tuner-FM-signal-strength of a cable used as antenna (while just hanging over your messy desk" says _everything_ about how that cable "sounds", this is nothing!
@@zulumax1 Well, if GR-research makes a claim that it does, he should at least follow that up with research that backs his thesis. He did not. From my background in physics, the situation of a one-ended, open-ended connection of a cable to the antenna-input of a FM receiver and what that receiver sees, has _nothing_ to do with an audio interconnect that uses both wires (signal and ground) and emanates from a very low impedance output stage.
@@TheEmmef There are follow up videos, and he keeps claiming to have proof, but proof of what? Keeps going down the same rabbit hole. There is more EMI broadband noise coming in through the power cord that could ever be brought into a stereo by a speaker cord wicking noise into the more sensitive high impedance high gain circuits inside which can alter the sound. Some folks use shorting RCA plugs on the unused inputs of their gear. Now that I can understand.
for a guy whose entire business model is making speakers sound better and showing us the graphs, it's hilarious that you can't show a graph of cables sounding better. Go do an A/B/X blind test and show us the results. Different tracks, different days, one of your cables and one of a $50 dollar pair of good quality 12 gauge twisted teflon coated Monoprice cable.
@@dannyrichie9743 what I'm not hearing is noise, you can't manufacture a problem that doesn't exist and then claim to magically fix it by buying expensive speaker cable. A/B/X test and show us those results. You know, the same way you show us the results of every crossover you improve? Consistency.
The inductance of a simple speaker cable is of such a low value that filter attenuation (treble cut ) to the -3db point would I expect be well over 100khz so nothing to worry about.
The answer all these guys have is, well your syatem just isn't good enough to resolve it. Danny basicly told in a recent comment because I'd never listened to music on a REAL system... My amp, dac, speakers alone are $2k, how expensive of a system is required to hear the difference of these cables...lol. I guess these cables are only for people with REAL systems
@@iowaudioreviews That's just bullshit. Turn on your system, max volume, no input signal (playback stopped). Do you hear any noise coming out of your speakers? I don't. I can put my ear right on the tweeter and there's just dead silence until I press play. 130W from amp, 83dB/1m/1W at the speaker. Doesn't matter whether my system is good enough for you or not, THERE IS NO NOISE. The only thing that's audibly susceptible to EMI is the signal cable due to higher impedances on both its ends.
Here's an analogy of measuring the wrong thing: It's like dipping a paper cup into the Atlantic Ocean in Nantucket, inspecting the cup of seawater, and proclaiming, "There are no sharks in the ocean, because I looked and found nothing."
Engineers can do a lot of measurements that can explain differences in sound but they are not part of the simplistic (and irrelevant measurements as far as EMI/RFI is concerned) required by the FTC Amplifier Rule, which is largely under enforced and ignored anyway. Scientifically performed and valid subjective testing is too expensive to do on a regular basis, which leaves the door open for unscientific demonstrations to "prove" that cables make a difference.
@@StewartMarkley a _good_ engineer, however, can do some practical measurements that _do_ make sense. To be really simplistic. Imagine that your speakers are 4 ohms and that we ignore the _actual_ impedance as a complex function of frequency.[1] In the ideal case, a modern amplifier is a voltage source. This means "zero" impedance and a high capacity of delivering current to keep the voltage stable even if the impedance of the load (speaker) drops to undesired lows. This voltage source is what modern speakers are designed for. If your cable is 2 ohms, the speaker does not see a voltage source, but instead one with 2 ohms in series. BAD. It means that the cable will become warm, as it eats at least a third of the power. Warmth increases its impedance, making the situation worse. As long as your impedance is less than, say, a hundred times that of your speaker, nothing can go wrong. Parasitic capacity does not play a role, because the whole exposed circuit is connected to a voltage source with almost zero impedance.[2] If the cable somehow manages to have a high inductance, this can be bad. However, you probably would have to wind it around something on purpose to make this a practical problem. A good engineer knows all this. Use a good combination of thickness and length and it will be okay. If a cable has "sound" it is an inaccurate cable. If you _like_ that inaccurate sound: go buy the cable. Many people like the "warmth" of tube amplifiers: go for it! ____ [1] I use impedance consistently, as "resistance" is only the non-complex part of impedance. A resistor with a capacitor in parallel is a circuit with a complex impedance that changes frequency response and phase. A speaker with a crossover and two drivers is a hellishly complex impedance. The goal of an amplifier is to keep the voltage across the speaker terminals an enlarged copy of the input, _no matter what._ [2] The voltage source is not ideal, of course. The damping factor is probably guaranteed for 20-20kHz, however above that it could be much lower. In that case, parasitic capacity and induction might even help to mitigate "reception" of radio frequencies.
@@TheEmmef As an audio and RF engineer with 50 years of experience in those fields, I am quite aware of the technical issues of amplifiers, cables, and speakers. My point here was to point out that while measurements can indeed explain the differences in sound, the kind of measurements that are needed are not something that is done or at least provided by the industry. Also, the measurements defined by the FTC Amplifier Rule do not encompass those measurements, and that the FTC does not even enforce the current rule anyway. Therefore there are no measurements done and specs provided to help inform the customers that might even care about this anyway.
You basically showed how a transformer works and that cable geometry affects magnetic field direction. Nobody winds their speaker cables into coils designed to create a magnetic field. This doesn’t explain why you need to buy 1000s of dollars of speaker cable. By the way, an oscilloscope is an observation and is not equivalent to licking a wire. You are observing the real signal in a visual manner.
Yes it’s very dramatic! I think the reason people make videos showing these cable affects is to sell thousands of dollars worth of cables. I guess you can apply this knowledge to any cables?
Truly demonstrated how a trafo.. works.....😉😉😉IF THAT coil was done with real speaker cable/ power cable... 🙄🙄🙄🙄 no transformer action would be seen😂😂😂
Danny, you forgot to "educate" everyone that an inductor is just a piece of wire that has been wound into a looping structure (usually a round coil). The key difference between speaker wire (and any shielding) is that inductor wire is insulated on its ENTIRE LENGTH (except the very ends where you connect the leads). This insulation is the "red" coating that you see on your inductors in the video. Whereas speaker wire, and any shield surround speaker wire is made out of bare-wire that is not insulated so that it can conduct electrons as best as possible (which is the speaker wire and any shieldings job). Comparing an inductor and the physics of its operation to a bulk conductor in open air is very different. Your demo about coupling in inductors is one thing, but then switching horses to speaker wire acting the same way is very misleading. en.wikipedia.org/wiki/Maxwell%27s_equations can show the way.
@Marten Dekker @Marten Dekker Yeah, this logic jump is amazing. A long-wire layed out flat, like a typical speaker cable has virtually no inductance effects...like infinitesimal. Rather the capacitance between it and any parallel conductor (like in lampcord speaker wire) would be the more dominating effect, and arguably that capacitance effect is negligent and immaterial to the end-result. But yeah, comparing a inductor which is made out very tiny insulated wire, all wound up...to a big gauge multi-strand speaker cable (with or without shielding) that is laid out mostly flat is apples to oranges headscratcher for any electrical engineer. . As for cross-overs...well, there is some "art of the compromise" I feel for speaker designers to get a good final result...but these videos aren't discussing that topic at all...rather somehow comparing the magnetic coupling w/ inductors to speaker wire, which if anything is capacitively coupled. Need to go back to basics and explain to people what's actually going on /w physics....none of this has to do with speaker wire's main job is to push energy to the speakers over a distance. People can solve this concern buy just buying active speakers that are becoming more popular. Then the distance of the internal wiring to the drivers is super small haha. Expect Danny would probably like to examine and upgrade that ~1 ft of wire inside the cabinet though :)
You have a gentle way of pointing out the false logic here. I wish I had your tact. It’s hard though when you’ve heard this garbage recycled over and over. Why can’t a guy just stick to marketing speakers that can sound nice? A grandiose ego perhaps?
This is a 100% ridiculously pointless test, it has everything to do with a coil of wire with power flowing through it, I.E. an electro magnet, setting next to a coil of wire connected to a speaker... Everyone that has passed a basic electronics course knows that a magnetic field near a coil wires can generate a current...which is all this test shows, it has nothing to do with speaker cables at all. What you are displaying is EM transference, also known as inductive coupling, not RF.....
also, can't what is shown in the test be taken care of with component shielding and also shielding the crossover from the outside world? Amir, of Audio Science Review tested the RF idea, in wires and according to what he measured, the RF isn't perceivable because it is beyond our range of hearing. I still wonder if the ultra high frequencies of RF could impart a "character" to the electrical flow. Of course there are other things that could disrupt the electrical flow, as well... The question is, unless you are listening to planar magnetics or electrostatics, could you even hear it, with say a paper cone, if the inaudible RF is imposing itself on the electrical flow ("sound")?? I am just not sure if it is even audible on audio "devices" with higher moving mass. A paper cone, vs. a planar magnetic diaphragm = two different worlds..
I don't normally do this, but I just had to watch this again and wrap my head around it. And I also am not normally derisive of anyone, but I think I figured it out: Danny knows just enough to be stupid. I don't like saying that as we all have our limits, but I think its true. The experiment thus presented is valid. The coils will act as an air cored transformer with varying degrees of efficiency when put next to each other due to mutual coupling of their magnetic fields. Indeed audio transformers do just that via magnetic coupling and provide the useful property of impedance transformation. However, unravel each coil until the magnet wire is straight, and lay it next to another unraveled coil, and the mutual magnetic coupling will be infinitesimal at audio frequencies. Like its not even the same thing. What are we actually trying to show? Its like saying: "Here I can prove string theory. Watch me play checkers. See, its completely true!" The test as absolutely nothing to do with speaker wires.
Yes, the same thing can happen with speaker cables. See what other experts in this field say: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_rWLCSx0Zuw.html
@@dannyrichie9743 Here's an actual video on the topic, with demonstrations: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TVCmPrDthlE.html I personally would have used a power cord connected to equipment since the effect would be more dramatic once there is sizeable current flowing, but its still valid. You are absolutely correct that magnetic fields can couple into speaker wire, but there's the important concept of _node impedance_ in electronics. Magnetic coupling will only be an issue near power line frequencies and their harmonics. You can calculate the relative magnitudes by the intrinsic impedance of an amplifier output, which is only milliohms at low frequencies. Furthermore, the amplifier has ENORMOUS loop gain at low frequencies if its a linear one. Therefore anything that does make it thru, will be squashed into oblivion by feedback. The only place you will experience intense interference on the speaker side is at high RF where the amplifier presents a high output impedance. This is especially a problem with the speakers themselves since they just have single hookup wire in them to tie the drivers together, and they make great antennas at RF. Effect is easily demonstrated by leaving a cellphone next to a speaker. Often you will hear a clicking sound in the speakers. The place where what you say is absolutely an issue, is at the input of the amplifier, where impedances can approach 500kΩ, and there's not much there to resist anything that couples in.
Because neither of those two things will show the claimed differences. When you have to dance around with inductors and AM Tuners to laughably attempt to sell people speaker wire kits, you've already lost.
Damn my man. Amir smoked you with facts. Science and what’s not science. I’d take videos down if you’re smart cause this is going to really hurt your business without a doubt. You’re basically saying that info is wrong, but there’s no rebuttal using facts and using a specific scenario that isn’t realistically applicable. Every comment is saying you’re basically purposefully generating results to justify your point and defend your position. None of this disproves or disputes anything Amir brought to the table....
Anyone that knows anything knows Amar brought nothing to the table. I know a lot of people in the industry that got a good laugh from his video's. He only confirmed the things I said and then theorized a conclusion. He did nothing. But it was funny.
@@dannyrichie9743 Argumentum ad auctoritatem and argumentum ad populum are all I'm really finding from your replies. I like you and I do think you're onto something but I can't say I've heard you make an objective argument on the subject yet.
Labs that I am aware of consider oscilloscope measurements to be objective science. These instruments are not subject to psychological bias or Mr. Wizard Mumbo Jumbo.
@Douglas Blake Another BIG hint: Identical electrical signals fed into a particular speaker will produce identical sound that leaves the vibrating cones of that speaker.
I give up, I am selling everything. None of the 20hz to 20khz components I own are built with RF shielding, the speaker terminal, the crossover, the power supplies, the circuit boards etc., I have been listening to distorted music disguising itself as pleasing. Thanks for bringing it to my attention. BTW do you shield your crossovers from RFI? Because it will penetrate the wooden speaker box.
Not everyone has hearing good enough to make out the more subtle differences that cables and shielding etc can bring. Count yourself lucky, it will work out much cheaper for you.
@@garywright8137 another factor is that not every system will resolve the differences that cables make. Just as poor cables can mask subtle differences in the music, poor components can mask subtle differences made by the cables.
Dont give up. This is a great hobby. Follow the undeniable facts. Ritchie is conflicted. He doesn't know if he believes in science or not.. His speaker designs/reviews/ and crossover upgrades are solid.. Discard the rest about his "magic" components..
Another fun fact: If engineers can make plain old 2 sided PCB's that work into the 100's of Megahertz range with low amounts of received/transmitted EMI then a loudspeaker system can be competently designed to work in the 4 to 8 ohm range @ up to 20Khz! 😉🤣🤣🤣
8:50 : Run exact same test by substituting the transformers each for left and right strands of standard (cheap) speaker cables. I suspect you would not be able to hear anything from the tweeter, nor would anything be measurable because the inductive coupling would not result in any output signal being above the noise floor. This is because the inductance of the speaker cables is orders of magnitude lower than the inductance of the inductors used in the experiment most likely. This makes a huge difference when amplifying a .001V (1mV) or so signal by 1000x such as from a moving coil cart by a phono preamp, however a speaker signal does not get re-amplified and the signal level itself is already high compared to the ambient noise being induced. Not a critique, just an observation; love your vids. Cheers.
Nice to hear your input as an engineer on this channel stereopolice. One thing to think about is the broadband noise is feedback through the negative feedback line from the speaker output to the input stage of the amplifier. I think Danny mentioned this in one of the videos. The very high frequency noise could potentially ride on the input signal. Although the signal is not audible it could be plausable that it could be passed as lower frequency noise into the input signal changing the original signal. There are low pass filters inside amps to filter out RF, so this may be a mute point.
@@zulumax1 right on brother, the type of noise you refer to is usually eliminated by the resistor in parallel with the inductor in series with the output of most Class A B amplifiers and other amplifiers you will see it on most schematics and that's why it's actually there, for stability because of the negative feedback circuit and the poles.
You would get capacitive coupling, but it would be in the pico farads and the impedance would be way too high to have any output into a low impedance circuit at either end, source or load, amp or speaker. Now the high current signal from the amplifier could induce a bucking current through the adjacent conductor, that is more likely to have an effect. I just retired from a company that my job was building cables and wiring harnesses for aircraft. We built many with twisted multi-conductor sets for low weight and noise reduction. What he says is true, but not relevant to what is being heard, in my opinion.
I regret not watching this earlier, because I'm laughing so hard! Reminded me about the experiments made in primary school. This sophism is so wrong that I cannot even describe it. So just because there are magnetic fields that might interact with each other, then a cable changes the sound.
You should go over a sort of good, better, best at different price ranges for cables. I think anyone can agree that less noise in a cable is better, but at a certain extent, having $500 in cables and $100 in speakers probably won't sound as good as $100 in cables and $500 in speakers, so a recommendation as to how much you should have into your system before going for each tier of cables would be helpful. I think a lot of us here are interested in the DIY aspect to get the most bang for the buck and knowing when and what to upgrade could help a lot of us.
Don't go by price, especially with cables. Focus on sound quality. System matching is everything. Its very common to prefer a cheaper cable over an expensive one.
Well, obviously. More expensive ALWAYS means tighter bass, clearer treble, lower noise floor, more detail and all that stuff... There are no exceptions.
Of course it sounds better, mate. Your system sounds horrible! But with this new $1000000 cable, everything opens up! The sound stage opens, the re is detail in the highs, angels come through the speakers and caress your ears...
I' m agreeing with David Long about this video. Many of us understand emf interference in regards to inductors as well as parallel conductors and do not dispute what you are saying. However, the issue is the matter of the audible and measurable effects of emi or rfi for the lengths of speaker wire in a typical home environment in which the amp to speaker conductor isn't running parallel to a high voltage and current carrying cable or an object putting out more than 1 watt of rf. One thing for sure is that the capacitance is increased with woven, braided, or twisted pair which means at certain lengths they act as an ac frequency filter as well as one that rejects interference. Which is a shame when it comes to attempting to connect a phono cartridge to a phono preamp because everything you are talking about becomes extremely important because the signal output from a phono cartridge is at the same level of emi and rfi of a typical home environment. There is no doubt that the speaker cable you are selling is great at rejecting interference and I wish a similar construction could be used as phono interconnects without the increased capacitance being a problem. With all that said I am not rejecting the possibility that speaker cable differences can be heard. However, when it comes to cost I think for most people the extra expense would be of more use when spent on better drivers, baffle design, or crossover components.
I think that David Long missed the point. It's super simple, and you don't need a full-range moving audio sample and speaker wire switch box to understand. In fact, this will confuse us. That's why he used a white noise tone and the simple four orientations to examine. Inductance coupling is all about wire orientation. Nothing more. This is the principle that most of us missed I fear. I've explained it more in my reply to Mr. Long.
At 8:07 the result with poles 90° opposed was "almost non-existent". Here you indicate what would happen if the same test were done using a straight run of basic speaker wire: a completely non-existent (or at least inaudible) change in the measured output.
Video number 3 without a double blind test of speaker cables. Come on Danny. How much power did you send to that coil? And did you send an RF signal or an audio signal? What did you prove with that test regarding speaker cables? Nothing! Nobody, especially no electrical engineer, doubts that cables act like an antenna and/or a filter. And most of us know how coils and transformers work. The question is if a tiny RF signal is enough change the output of a speaker which is connected to a big amplifier. Why don't you demonstrate that one? We are all waiting for that double blind test with an amp, two different speaker cables, and a speaker. I am sure you have all those things right next to you. Why don't you do that test and show us the difference? Double blind. Can you, the expert, reliably detect the difference between a good cable and a special super duper speaker cable? Show us!
So you think you proved that speaker cables make a difference by playing with the inductors and NOT swapping the speaker cables? That's like proving a different transmission in your car makes more horsepower by changing the tires. Sorry, this is NOT science.
r u being dense just to be a jerk? if you are unwilling to see the parallels here then you are not in the right place. current is current in a wire, it can pick up noise and transfer it. period. how many hi end cables have you a/b'd?
@@veroman007 I'm pretty sure it's you that is the dense one here, EM transference from an electro magnet into a coil of wires is simply inductive coupling and learned in freshman Highschool basic electronics, all this video shows is inductive coupling and shows absolutely no RF transference at all, had he laid that inductor next to speaker wires connected to that tweeter rather than an inductor, no noise would have been heard, Danny is a snake oil salesman that knows he has an uneducated audience, and he plays it very well to sell way overpriced sound deadening mats, crossover components and wires to simpletons that don't understand how he's lying to them....There are no parallels here between what was shown and what was claimed.
@@veroman007 The principles shown in the video have been known and measured for well over 100 years. That's why crossover networks use coiled wire and speaker cables run parallel. A simple, definitive test would have been to swap the speaker cables (with an audio amplifier driving them into a proper load impedance) and then watch the scope and listen. I suspect the difference would be so negligible that nobody would be able to see it or hear it. I'd be happy to be proven wrong. You might want to learn some basic electronics before putting your ignorance and lack of manners on full display.
Lets do a simple test. Any amplifier fed with a 10khz square wave at a nominal 5 watts output. A none inductive load resistor. Scope across the load. Test 1 connect the two via 10 feet of normal speaker cable, look at the output. Test 2 same set up but use the super wonderful cable. See which one makes the amplifier ring most?
You have to address the following: 1. The fact people are not doing blind tests, and the fact that not doing so absolutely messes up the science of your test. In your own words, you're measuring the wrong thing. 2. The magnitude of everyday EMI/RFI on the wire acting as an antenna, and what that is relative to the signal on the wire. SNR matters. 3. The simplicity of a simple test of listening to a blank signal on a system and seeing if you can tell whether the system is on or off. Is there any EMI/RFI to hear? Remember to do this test blind.
I've been generous and watched all the videos to date in the series. What you have done is proven that this _is_ a difference. No one debates this. What is debated is whether this matters in an audible way that passes a simple blind (or double blind if you're diligent) test.
Someone explain this to me. If my speaker cables are indeed picking up unwanted noise (RF and what not) and if it is indeed audible, then I should hear that noise even if my system is on standby (meaning amp and source turned on but nothing playing) correct/no? Yet I put my ears inches away from my speakers and they are dead silent.
I always go after these guys pushing magic cables. Usually end up being told my system isn't gold enough to resolve the improvement.... I guess these cables aren't for everyone. I've done the same thing and my system isn't ridiculously but it isn't cheap crap. Hok up some basic zip cord toss it out on the floor over some power cords and whatever. System on, nothing playing crank it up and nothing..... These EMI and RF frequencies being picked up by the cable must only effect things while music is playing.... what about the wires inside the speaker cabinet.... if I moved to the Alaskan Klondike can I use regular cables since theres no interferance up there. Probably cost less than Dannys system.
You won't hear the noise itself so much. What is heard is what it does and how it effects the audio signal. Tune into the next episode and I will go over it more.
Yes, despite what Danny claims, you would HAVE to hear some sort of noise if any of this were an audible issue. The fact that you don't is all the proof you need to know that this is a crock. If it wasn't obvious by all the convoluted "experiments" being performed in a bad attempt to imply that something unexplained is an issue, when he could just as easily actually measure the two cables, the the fact that you hear nothing but silence in your system is all you need to know. If you turn your speakers on and hear an AM radio station then you have a different problem that nothing Danny is trying to sell you is going to fix.
I was 15 knowing nothing about Science of cables. But I could hear a tone in my speakers that was not part of the music. Having little money at that age and all ready discovered different wires single or multiple strands copper or steel or close or separated using my father’s and grandfather scrap wires in the garage using my ears 👂 and the power meter on the radio signal strength meter I found the best wires for the AM & FM Signal. I had Old used speakers from a very old system paper cone speakers. At the time at that age I knew nothing about speaker efficiency that those used old speakers came from a system in an era where speakers had to be very efficient to work on low powered amps. So my speakers were naturally super sensitive to any kind of electrical input and you can hear it with your ears even though they were salvaged from an old system decades earlier and thrown into a big open box that I made as a young teenager with no knowledge of crossovers or speaker enclosure design. So when I noticed the tone not part of the music playing through my speakers when I moved my wires around in the back of the system I finally figured out it was coming from and into the speaker wires being close to other wires or even the aluminum window frame of the window. That’s when I went back down to the garage to get my grandfathers and my fathers different types of wires and started switching out wires until the noise went away and that’s when I discovered I can hear the difference in musical instruments by switching wires types and materials. But I was a kid with the hearing ability to hear a TV turn on with no sound on , just electronics high-pitched tone while walking in the street through the walls or windows of houses as I’m walking outside. Can hear a wristwatch ticking stuffed inside a rolled up sock hidden underneath the clothes in a dresser drawer across the room. Can hear bugs walking. I definitely can hear the difference that the materials and make up of wires on music to make. But now at 56 and have a slight case of tinnitus years of working with loud IMPAC hammers and wrenches in a mechanic shop my hearing starts rolling out at 12,000 Hz and totally deaf after 15,000 Hz. But surprisingly in extreme cases I can still hear the difference on really high and very resolving systems cables still make a difference with my bad hearing. In the soundstage and the depth and the resolving revealing of details within the frequency band I can still hear. But on a big box store high volume cheap system AV receivers under $2000 system I really can no longer hear any difference because the system does not have the ability to magnify the difference. Some people are lucky they were born without the ability to hear tone difference in here fine details in sound they’re lucky because they don’t have to spend any money on good speakers they don’t have to spend any money on cables or high and systems because they don’t even possess the ability to hear the difference they should consider themselves lucky at not having to spend ungodly amount hour of time and money because they’re basically Deaf to find tones. The science a 15 year old can even figure out and hear
Old TVs would always bug me as a child, high pitched sound they made drove me nuts. It was nkce when flat screen came along. I have an above average system and have made many different types of speaker cables and never hear any repeatable difference that could be proven with blind tests. If it really is the case these cables are only the 1% I guess.
I remember those days.. when the tv was on, I could hear everyone in the house moving through doorways, hallways, and in front of the TV, etc because that high pitched sound of the tv changes whenever people move around

@@coldfinger459sub0 I have been on a panel of listeners on blind tests. One cable changed, recording replayed, and everyone on the panel heard the same change at the same time and said "woah".

When I was younger I would walk into jewelry stores and those ultasonic motion detectors would drop me to my knees. People would say "You are not supposed to hear that, it is above the range of human hearing". A gift or a curse, one wonders....
@@zulumax1 I have to25 foot long speaker cables that I bought from RadioShack when I was about 15 years old. They were lost for decades and re-found in my mom’s basement several years ago the rubber plastic vinyl that was clear is now semi translucent and was very sticky and Gummy deteriorating but I cleaned it off with alcohol to get rid of that stickiness. The copper that you can clearly see inside has turned all green and flaky and corroded. I clean the ends and used it as an A.B. test just for that very reason believe it or not expensive does not mean better , you are correct. Nobody can ever replicate or reproduce that green corroded flaky oxidized copper , insulating deterioration RadioShack 10 gauge speaker wire is priceless. That is 41 years old
Just to make sure we are all on the same page: The term "cable" being referred to here is the "wire" which connects the amplifier speaker outputs to the speaker, not an RCA interconnect. Seems to be a lot of confusion here on terms used. Bought my first "Kimber Cable" 8 conductor black/brown speaker "wire" in 1983, still have it. They have actually been around for a long long time. I always assumed it was the expanding and collapsing magnetic field surrounding a speaker wire caused by the ac music signal traveling through the wire that effected the sound. Low impedance circuit there is going to be a lot of current, any current caused by RF would be squashed, just not strong enough field to produce current. Not saying it doesn't sound different, I am saying the conclusion is flawed.
@@dannyrichie9743 I hope you are monetizing this series, because you've drawn out all of the ASmiR folks like flies to shit. They are trolling you to drive traffic to The Science Channel. Let's not encourage them.
Why not go the easy way of connecting one of the expensive cable and a normal cable in a normal manner how normal people use it and then take a measurement using a calibration mic. Normal People dont wind their speaker cables into an aircore inductor and place it on top of each other.
David Long basically asked the same question. It's quite simple (I hope so anyway) from my perspective. He's trying to demonstrate inductance coupling, and this is a perfect way to do it. Part 2 below might be more to your point. 1. The measurements are on the screen. He is measuring the dB differences in the different coupling orientations. We also hear it - the white noise. So he's following up on what's he's always said, that hearing makes the difference. I'm sold. 2. Why doesn't he need to change the cables or compare between the cables? Simple. He's teaching us the principle of inductance coupling, and using the inductors is much more effective for us to learn the lesson. So he doesn't want to switch between wires. Rather, he wants to reduce a full-frequency audio spectrum (say in music, which would make it difficult to hear the differences) to a single tone. We need to hear the difference because it's essential. The point to understand is that the principle will still apply in either case. In this test he's quickly able to adjust the orientation of the one (unpowered) inductor vs the other. Last note. Currently we do not have testing methods to measure coupling fields. I'm sure that one day we will. In an interview with Mr. Kimber he mentioned this. Nevertheless we can hear it in tests like this. Does that make sense?
@@nickburak7518 are you being serious or sarcastic, because I'm confused. Maybe i misunderstood the video title. I thought the video was about difference in sound and measurement between speaker cables in a normal stereo configuration. Maybe the video was about crossover design and interaction between aircore inductors. Or how you can use speaker wires to make inductors in crossovers. After all air core inductors are expensive. English is not my first language. Sorry for the mix up. I will try using google translate for the title.
@@berlyfredy7153 I'm being serious, my friend. Your English is good. I've been on this comments section all day, mostly trying to explain myself to most who, like you, can't believe I'm serious. To me, this means that they can't believe that Danny is serious. This means that most of the commenters don't believe Danny who is a multi-award winning designer. I'm sure that he understands more than anyone here by mile. Here's where I think everyone is making a mistake. Danny is using an example that doesn't work well for everyone. He's trying a new approach. It. Began with the flat earth thing, and he got trashed for it. I wasn't phased; I saw it as maybe not the best example. Then today he used air core inductors to explain interference blocking. Most people wanted him to compare the wires, but he can't show that in RU-vid, and not a single person knows why. I'll tell you why. It's because the RU-vid audio algorithm is mp3 quality 256 bit. That's not anything like CD quality, and forget about hearing 96/24. I hope that you know what I mean, because I'm not going to explain it. So even if Danny recorded in binaural audio we would hear practically no difference in RU-vid. In Cobuz or Tidal (through Roon or not) we can have high end audio. So what's his angle? He knows that counter-clockwise braided wire has the properties of filtering out interference from outside the wire that can leak into the wire. This interference could come from anywhere between a/c hum from power wire, radio noise, etc. So he used the example we saw. He showed us that if the wire is cross-oriented then noise goes down. The problem is that so many viewers think he was talking about inductors. Or inductance between inductors... Or crossover design with inductors. He wasn't talking about the inductors - he was using them as an example of the design philosophy of the braided wire he sells. The idea of braided wire or spiralling wire is not new at all. In speaker wires Audioquest and Kimber Kable - two of the best cable makers in the world - this is new. But it's really expensive and most of us can't hear the difference on our mid-fi or low-fi systems. That's who is arguing here. The men who have lots of money to own expensive high-end audio ($20,000 or more) are the ones who own this wire. These systems do sound better with this wire. They known its real, but guess what? They are at work today. They are not arguing in the comments section. But the owner of Kimber Kable, Ray Kimber is not the only person who is saying that even us ordinary guys with ordinary systems CAN hear the superior clean sound through braided wire. Problem is that most of the people here take offense to what I'm saying. I'm hurting their feelings. I sound like a know-it-all. I'm not a know-it-all, but I'm not gonna pussyfoot around. Danny is offering a great DIY deal for anyone who wants what would normally cost over $1,000 for maybe $200 ($500 if you want 40 ft.). But many people think that $200 is a crazy expensive price and think that Danny is trying to get rich selling wires that look like snake skin. He isn't. Danny Richie is offering us a very good value. Everyone is simply complaining about HOW he is teaching. Instead, viewers should think a little more and watch other videos or actually read some research. Even guys who are engineers are complaining. It's all the same thing to me: closed minds resisting a different teaching approach.
@@nickburak7518 buddy for you i will explain again. What i asked is not to do a recording of some music playback between different speaker cables and post it here. None of our ears are capable of perceiving a difference that way. What i really wanted him to do is. Arrange a speaker +measurement mic. Connect using an expensive cable. Play a sin sweep tone and record the frequency graph. Now connect a normal cable and do the same thing. If the graphs are superimposed on top of each other that means there is no difference. If one graph has a consistent improved response in a particular frequency range that means yes there is a difference which is controlled by the person who designed the wires and can be attributed as an increased sound quality. If the one graph is different but the difference is not consistent (which means at some frequencies the graph is higher but for some other frequencies its low and some other its same) that implies, yes there is a difference but who designed the cable have no control on creating a particular frequency response. This case you cant call the result superior, its just different. This is all i wanted and this is a fool proof method of doing it because even the pro cable guys say "we can HEAR a difference". So for everyone the end sonic result is whats important. But humans are affected by psychological factors such as confirmation bias, habituation, placebo and alot. In my profession we had an entire book which had the title "human performance limitations " and due to all these human limitations we were trained to "TRUST YOUR INSTRUMENTS". So A measurement mic has no psychological flaws compared to humans. Its fool proof and its more sensitive than human ears. So if a measurement mic cant hear it humans for sure cant hear it aswell. So if humans cant hear it whats the point of spending 1000s of dollars in cables. To impress your dog or a dolphin passing by your beach house..? PS -the book i mentioned is 1 of the 14 books which is part of EASA ATPL theory.
@@berlyfredy7153 Thanks for taking your time. I've made a quick look into sine wave tests, but don't have enough information just yet - the ones I've found are more like a frequency test than any kind of speaker cable test. But I certainly can appreciate that the right common sense tests help to reduce or eliminate bias as you and many here have contested. So perhaps I've been a bit sucked in by Danny Richie, being impressed by his XO videos (and awards)(but again, many more people think he's on point there). Perhaps there's a lot more self-advocacy ('sales pitching' as many assign to him) than I see. I see him as an honest guy - if he likes it he has no problem saying it. So I'll take a step back and verify what I hear and read from him a little more. Generally I don't accept something as valid until I've heard the same thing from many others as confirmation, and I find that I study/research a lot to prevent my accepting snake oil as truth. Over the last week I've invested a lot of time in learning about audio, and one realization is that this field is certainly filled with opinions. It makes it quite difficult for someone like me who isn't an engineer or an experienced audiophile to make sense of things. So basically, thanks. Feel free to read on if you like, but it's not necessary. Are you a pilot, btw? Is this where you learned a bit of physics? The gentleman who started Audioholics made a tongue-in-cheek video where the more money spent the better the speaker wire. He likes his Kimber Kable 8PR for its low impedance and low resistance. He instructs not to buy cable from a company that does not provide at least three bits of data (the resistance, inductance and capacitance). He mentions nothing about the filtering from a braided wire. Rather he does admit that there's a certain level of the 'jewelry' factor that influenced his decision to get the Kimber Kable. Having said all that he really likes the Blue Jeans cable, which I have, and thinks it's darn near the best value you can get. I've seen listening tests, I've read about listening tests, I've seen the data, and I've heard opinions. I've heard the sine wave test that you mentioned but, as of yet haven't found, I haven't found the holy grail of tests that quells all others. Perhaps there's no such thing but more of a combination of tests, both with mics and graphs and listening.
Yeah, of cource. Your Inductor has 0.2mH, a cable has 0.005mH. RF has less than 0.2mV, your speaker gets 50V +/-30V. You absolutely can compare that. If an inductor is inductive, a speaker cable has to pick up RF. This is like measuring your cars fuel efficiency to get an idea how much your bicycle needs. That really makes sense. Sry Danny, but you are the flerf. You are making stupid experiements to convince us. If you really belive in these cables, than make a real experiment. Take your tweeter, wire it up with 2m of 6mm^2 music cable. Measure as long as it takes to get less than 3% difference. Repeat it with the magic cable. Compare the results.
What about putting a ferrite ring over parallel-pair or twisted-pair speaker cable? It could be cheaper. Since there are many different ferrites, we can choose one that does not affect audio frequency.
Standard audio measurements would explain, The only thing wire can effect is overall volume level and frequency response due to its resistance, capacitance and inductance.
I'm a firm believer in the importance of cables (I'm a high end cable manufacturer). While I appreciate this series, I think you're not really helping to "prove" the important aspects of cables. You're just showing that different electrical specs will affect the cable. No one argues that. If you want to convince anyone, you need to show (either through audio demonstrations or measurements) that 2 different cables with the same electrical parameters (wire gauge, resistance, inductance, capacitance) are different. Show that everything you can measure from an electrical point of view is identical. You could even show yourself doing a blind test. Have a screen up and someone behind swapping speaker cables with you picking out which is which (repeatedly).
Great, a fellow cable licker. Why is this not proven already, can you explain that. Why you ask if Danny can do the dirty work for you. Really.....omg.
@@djmadrox7539 because I don't care about proving anything. All I do is listen. I also send out cables at no cost to studios interested in trying them out. Guess what? No one has ever not hear a difference with my cables. I generally don't mention anything for them to listen for and guess what? Their comments tend to be exactly what I hear (especially when I include prototypes that I know aren't great)
@@djmadrox7539 all that I'm probably doing is varying different electrical parameters that affect how things sound. I have no clue how well these changes would show up in basic electrical measurements. I suspect they wouldn't but as soo as you change anything (like make a cable 1mm shorter) you'll have a change on some level. The real question is at what level do the changes no longer affect what we hear. It's the same way that many people think that all amps sound the same if they have the same flat frequency response.
@@octilliondollars Surely, if you send cables that are "tuned" , aka add noise, that makes it seem more warm. If you tune it to add resistance, the music will sound softer, anyone can hear that. As log as you put enough noise to the cable, you will hear it, just as the manufacturer ordered. And the same goes to a extend to the amp manufactures, they tune their produkt to get a certain sound. Denon often choose the "flat" response. a bit cold to some. Then you have Yamaha, who tends to give the low and highs some extra. Marantz, pretty much the same as Denon, English designs, often sound warmer, like the Briston/Brightons i heard, they did not care the distortion was not 0,004% like the major brand did, no they went like 0,03 or 0,3. They sounded warmer, more lively. So, instead on going to wire path to get your dream sound it is maybe a better idea to get that sound from your amp, you just need to find it. Whatever you the, the industry loves you, they give you want you want, one way or the other.
Here's the thing... If RF were a problem in speaker cables, then you would want to couple the noise into both conductors to get the highest common mode coupling levels possible. But with your cross hatched cables, there would be a higher tendency not to couple the 'noise' evenly into both conductors, the way you would with a field next to some twin lead. You know, common mode rejection, really low load impedance, your chasing ghosts here. For your commercial installation example, EMI coupled from the speaker cable and through the amplifier. Yes, stuff like that can occur, but the problem can be addressed more easily with a full understanding of the problem and not by placing false blame on the problem.
Well if RF is not a problem, then what is all the fuss over? Are we creating an issue which has no merit and perceiving a problem that needs solving, which is a non issue? This is what I call snake oil, or magic elixir. Ignorance is a great sales tool to the salesperson with just a little bit of knowledge. Oldest trick in the book, that is why we need something to measure or test. If it sounds different and tests the same, we are measuring the wrong thing.
@@zulumax1 Yes, in this case, snake oil and GR Research will be dismissive and call me a flat earther. All of these things have to be tested blind with better than 80% correct results. Decades ago, I did a blind test of Belden rubber jacketed industrial appliance cable to my brother's elite audiophile cable that was comprised of several flat cables made up of twisted pairs. We did one channel driven and a switchbox that alternated the cables. Lengths were about the same. it was a dead heat. There was no 'one is better than the other'.
I'm confused why everyone is challenging Danny. So you heard the white noise tones, yes? Do you think he made those up? Do you think the measurements on the graph were made up or unrelated to the tones we heard? He's teaching us about inductance coupling. The inductor orientations represent the speaker wire orientations (from braiding to non-braiding). He does not need to switch between the wires. We can understand how one inductor oriented at 90° is very effective. That's exactly what the braided speaker wire will achieve. No?
@@nickburak7518 he said “more proof”. Until now, he hadn’t presented any at all. Listen up - Danny is selling cables. If he wants me to change my mind and buy *his* product too, he’s going to have to do a LOT of convincin’. Have you even seen this video? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dLghg0QXPzs.html
@@nickburak7518 But he fails to show that any of that actually effects or is even relevant to what you hear when actually using wires as speaker cables. He is showing random known things about the properties of wire, not that ANY of that is relevant to whether a $500 super thick insulated speaker wire sounds more "open" than a standard 12g or 14g copper cable. You are leaping to the conclusion that somehow inductance is having some micro effect on what you hear. I don't know about you, but I don't connect inductors to my speaker cables. Nor do I tightly coil them. What he did show, is that you obviously don't stack your inductors in a crossover. And that's the problem with all of these videos. He is showing various attributes of wire that are known and real, but so what? That's literally what every one is arguing in these comments. If inductance is such a problem, and as he's shown it IS measurable, then measure it on two different speaker cables while in use. Why do some other irrelevant demonstration? I'm open to the idea, up to a point, that the construction of a cable might effect the sound, but these demonstrations are distractions.
@@redstang5150 Well the proof is sometimes something that you have to make the effort to find, even if it comes down to learning with an open mind and understanding that the speaker is a teacher and not a salesperson. It's not about the price of the wire, or what it's made of or how thick it is. Nor is is about XO assembly. That's not what this video is about. Most of the viewers cannot overcome that he used coils to demonstrate the power of strand orientation because they want to see Danny use the cables to show the power of strand orientation. Thats something that you need to understand. That's why Danny did that. It's not about insulation or sleeving technology. That's what is being misunderstood. It's about the natural filtration that goes on when the wires cross over each other at angles approaching 90°. Certainly you can't make a 90° rotation in the cables as there would be no dimension in the length, but maybe they are criss-crossing at 30 to 45° - even 10° I bet would be significant. I'm sure that you can think on that. I'm not trying to argue; it's simply that I understand how simply perfect the video was.
@@nickburak7518 What on earth are you talking about? This video series is about ONE thing - why (the quality of) speaker cables matter! And that implies that a more expensively constructed wire will somehow outperform a competently constructed inexpensive wire IN A TANGIBLE WAY. We all want to know. Therefore to show that they do, you have to be presented with a reasoned argument and some evidence that is relative to what you are trying to show. I could make lots of analogies to what Danny is doing here; i.e. by showing real properties of an attribute of an item, yet not showing AT ALL how those properties are relevant when they are actually used in the intended use case. Ok, so it is already well known that inductance exists in coils. Super. The question is if that matters and how it could potentially interfere with how a straight cable sounds. You can't simply infer that because it exists in scenario A that it must negatively effect the completely different scenario B. I'll repeat it again. Everyone totally understands what he is demonstrating here. What people are questioning is whether it is relevant to the goal. And no, the speaker IS a salesperson. Others can argue about whether he is being genuine, but you can't forget that he and all the "experts in the industry" that are his sources have a vested interest in getting people to believe that buying their cable will make their speakers sound better. My mind is open. I'm DYING for some real, relative evidence here, but we haven't gotten any yet.
Don't coils induct hundreds of times more then just parallel runs of wire? I know there is cross talk, but to compare it to 2 coils sitting on top of each other is disingenuous. I've had long runs of standard speaker wire runs sitting ontop of each other and not heard audible crosstalk in a system. Just shielding those cables pretty much eliminates anything. Not a Flat Earther, just asking. Can you do a test showing the induction between 2 lengths of wire running parallel having as much crosstalk as 2 Inductors, or anywhere close to it?
Yet another bs cable video. Inductive coupling between two coils is not the same as saying you can hear a difference between low resistance power cables. You are comparing apples to oranges. You might as well believe the earth is flat. Ohm's Law Rules.
All jokes aside - yes there is a difference between a crap wire and a good cable. Problem is that a good cable is relatively cheap to produce, but Audophool companies are promoting snake oil to get the suckers in. If you bought a $23 000 system, then yes - I understand that you would want a several hundred dollar set of cables. I mean, it'll look prettier compared to a $20 generic cable. But don't lie to yourself - it is just a dress up. And this guy once said in a video that he used cryogenically frozen wooden cable stands (wow!) and he heard a difference. Just no comment there.
This is not a valid test. First RF stands for radio frequency. you're talking about radio frequency like you can hear it, you basically can't because RF is from 20kHz to 300Mhz which is above human hearing in the best of us. As we age that goes down , way down. At 60 years old you probably are around 13 to 14kHz at best. Next, you're showing induction between two coils which is entirely different than two wires together running 5 or 10 feet. Next you're showing an elaborate wire pair with crossing wires or whatever, not only haven't you established the effect of two wires run next to each other in a test but you haven't tested simply moving two wires a few inches apart in free air. If you want to prove your wire is actually making a difference you have to do it in a DBT, that's real science. Before you do that you should display a graph of your hearing response so we know what frequency range you can actually hear scientifically. Right now all we have is a theory that proves and establishes nothing beyond how a transformer works.
We've already well established that the RF noise effects the signal. And the illustration was to show how fields interact with one another depending on direction. And all just laying the ground work. More to come.
@@dannyrichie9743 Who's "we"? And exactly what is RF doing to AF signals? Why are you using loops of wire when you can use the exact conditions? Put a 4 ohm resistor at the end of a 10' length of wire and see what you get. Then move the two leads 6" apart and see what you get. Heck run 300 ohm ladder line if you like. You're creating a condition that is abnormal, even if it was normal you could easily remedy it with shielded speaker wire but I wouldn't waste my time doing even that. Have you proved it in a DBT? Where's the empirical data? All you have shown is that split bobbin transformers work.
The phone companies knew this. That's why we have CAT5 and CAT6e cables for networking. It shields the wire, not making it a filter. A filter implies that it will still be an antenna.
Million dollar question......don't the cables of the drivers of the line arays going to the crossovers pick RF , electromagnetic waves etc.....why do u use just normal simple thin gauge cables and u don't use these?
It's up to you... Sure hard working people change everything with different solution & combination for each speakers. Only u set where to stop the work.
It's not about wire thickness - it's about wire proximity to other wires which influences inductance coupling. He's teaching us all about orientation of wire pairs (or 12 pairs in the case of the 8 gauge wire) that are right next to each other. Remember, on the floor and behind the audio rack there are all kinds of wires in close proximity to each other, so this filtering is essential to the highest Fidelity because the branding is the key. This is where most of the RMI & EMI's will be filtered out. His crossover designs, as we've seen, also account for that... And then, within the speaker cabinet, there are just a few single wires that aren't really next to any other wire, so inductance coupling should not be a problem there as well. At least, this is what I've learned from Danny. Corrections or confirmation anyone?
@@nickburak7518 No. Speaker cable is non-insulated, so it like a long piece of shorted metal...each individual strand can freely conduct to any other individual strand in speaker wire. This is it's job, to deliver power. An inductor like shown in the video is constructed totally different, it is a big coil of tiny --insulated wire--...because of it's construction and use of insulation on the wire it's inductance is very very high (that's why it's called an inductor haha). In a speaker wire laid out mostly flat, there is virtually no inductance...rather capacitance with any parallel conductors in the primary effect and that also is pretty infinitesimal in lamp-cord style speaker wires.
@@PhuckHue2 Yep. I got my degree in electronics and most of this is an anxiety disorder causing people to perceive differences that absolutely don't exist. I've seen a 3 dollar hosa cable put on an oscope and it was dead flat from 0-200khz. There is just nothing a cable can do to contribute to the frequency response until we start talking about 1000 meters of it or something like that. That isn't the same though as a guitar cable though which will start sounding different after 15 ft.
I think cables make a difference but only if you have the rest of your system at a high level. Some people spend thousands of dollars on cables but only spend a $1 on room treatment.
Speaker cables MAY make a difference depending on a given situation of equipment, cable layout, EMI/RFI field strength, and personal sensitivity. It doesn't depend on the sophistication or cost of an audio system, a Radio Shack system can be influenced by EMI/RFI in an audible way, although a small amount of EMI/RFI field strength may well go unnoticed in a low-end system but noticed by a person with a large expense and interest in the sound.
From now on, I'm going to wear a tin foil hat when listening to music ... I don't want RF interference in my ears. I plan to sell those hats for $1,000 apiece ... get'em before the price goes up folks! 😜
PLEASE HELP me understand why you use thick and often shielded speaker cables right to the speaker and then inside the speaker, near the magnetic coils and so on, do you use thin unshielded cables? :-)
So "noise" can permeate our cable. But how much of that noise is amplified? It should be easy to hear the noise all by itself, if it exists, by turning up the volume on any input. I think you'd have to go up and cup your ear to the drivers to hear the differences in various cable changes. But you'd be unlikely to hear it from a normal listening position with music at midway levels. That last measurement you made with the coils probably represents the real-world levels at which the cable world is splitting hairs. Sure, it's measureable, but at an almost totally inaudible level.
Hello Danny, I didn’t care much for Audio Science Review website, especially the followers of ACR (I don’t like conflict) which is why I hardly visited the site. Audio Science Review is now on RU-vid. I really wanted to hate Amir guts, but to my surprise he comes across as a nice well intentioned person and like you tries to bring clarity to us users on the audio product that we love and like to use (can’t fault or hate that). I think the truth lies somewhere in between the data and measurement and the actually building testing and listening. Stay safe, Brian
Frosty C. Danny is right on point. The science is clear and you don't need measurements on paper to prove it. Nevertheless he provides meaningful measurements and - most importantly - the hearing test. There is no truth 'somewhere in the middle" as you say. Simply put, wire orientation matters. End of story. Otherwise you would be going up against titans like Kimber Kable and Audioquest if you disagree with Danny. It's these guys who know what they are talking about, not the guys here in Commentsville.

Try a double blind test. If YOU or OTHERS can pick which cable is which your argument is valid. Otherwise its sounds like marketing mumbo jumbo you yourself talk about when discussing crossover components. All do respect but you don't know enough to know your wrong.
@@dannyrichie9743 saying you right is not scientifically valid proof. Now your being willfully ignorant. If your right, prove it via blind test and actual test equipment. Quoting a cable manufacturer website is not a valid test.

If speaker wires made a huge difference, it would be on display at Best Buy.

Maybe Monster Cable just doesn't have the marketing budget.

One of my questions would be, is there something within their hearing that doesn't allow them hear properly. Or could be simply be set so strong in their ways that doesn't make any difference whats being said.
@Douglas Blake well but think about one thing, u live in your house and ur ears are adjusted to the noise and echoes and reverberations in your house or room, u can even hear when when u walk from room to room or from room to a hole way or stairs etc how the sound changes, think about how much time u spend in ur own space and how ur brain decides to ignore the things u constantly hear and then think about if there is any small difference if u could hear it in your listening space, i bet u can! what u measure is sine wave and frequency sweeps? does that tell u anything about the interaction between ur speakers and room acoustics? even the slightest change can have an effect on the acoustic response of ur speakers in the environment ur used to hearing them, also music isnt a frequency sweep neither a sine wave test, the best way to measure is what u hear from ur speakers with two microphone at your listening position, why? cause music and sound is really complex with multiple frequencies at the same time and not just a simple sine wave, so far no one actually did any measurements of a WHOLE system well set up in a good room with all cheap cables from the wall to the speakers and compare the same system with higher quality cables through out and measure again, i bet there is something to be find.....
@Douglas Blake lol well I'm speaking ur language not mine so i guess ur nowhere near my level in my language anyway... yes it's been done alot but not for this purpose, it's just funny how always people with no experience seem to know all the science behind things, one question for you, did u ever try any expensive cables or ur just guessing it makes no difference cause of some science no one actually understands apparently so far, and also if the science behind measurements is so absolute why not take a trip way back to basics and ask the question "what is an electron and how does it look like" if u find any conclusive information on that then we can say that what we measure is real, but since we don't even know what's under our feet then how do we walk...
@Will lol well, but no one actually knows what and how an electron looks like or is, were just imagining things don't we, if you can't trust your hearing how can u trust measurements...
@Will lol well that link doesn't describe anything nor it shows any scientific proof of anything, the point is we cannot measure what we don't fully understand, simple as that, if people don't do practice is simply not science, same as practice vs theory is almost never as the theory suggests..
I think the issue is copper wire from Rat Shack or off the loom at Lowe's isn't going to sound HORRIBLE to most people, heck not even to me. It's actually fairly hard to get HORRIBLE audio nowadays, but there is MUCH BETTER quality audio experiences to be had, if you know how to set your room up, and pick the right equipment. I recently had to grab some 14ga copper wire from Lowes to use an amp that I hadn't touched in a while and did not have banana plugs on it. The sound was fine, deep and wide soundstage, instrument decay was there, dynamics were as expected, blah blah blah, it sounded fine. I changed amplification and saw improvements across the board, nothing glaringly wrong with the presentation, just an improvement over the previous amplifier (most notable was the control over the woofers so bass was deeper and tighter). Now with the new amp in place I could use my banana plugs again, so in went the Mogami cables which are not terribly expensive, maybe $225 or so for the banana terminated 10 foot pair. I wasn't expecting much at all, but what I got was a bit more of the top end and overall clarity. In general terms the Lowes cable sounded a tad duller to a degree. I don't have a problem with etch or brightness in my system, the sound was a tad livelier. Kind of appropriate I think for the difference in cost. Nothing magical or monumental but a tad better. If I hadn't swapped it out, I doubt I'd ever consider that the sound was lacking. I wasn't looking for it, I just noticed it. I'm not in the "good enough" crowd in the sense that I'll go bargain basement on things, I like well constructed devices and materials, so a couple hundred for good speaker cable from a reputable brand made sense, and in the end it actually made a slight DIFFERENCE. There's a crowd that swears by interconnects and speaker cables made from twisted UTP ethernet cable. I just haven't had the time (I've got plenty of the stuff on a spool) to try that out, but apparently it sounds good. Danny's implementation seems to be along the same lines but taken to another level. Personally I need to try it out myself, the problem is that I have the room arranged in a way that those snakes would become a trip hazard. Time to finish up some work so I can get some seat time with my rig.
High (speaker) level signal across UTP cable is a stupid idea. It might make the sound different, but definitely won't make it more true to the source (therefore objectively better). You want low resistance and UTP is just not that, because it's designed for a completely different purpose.
The whole point of listening to higher quality components is to recreate the sound stage . If the recording is 100% then everything in the system has to be 100%. If your power source is noisy and your components can't filter out that noise you have to call the power company and or an electrician to start. Can we get some price per performance components. Like a good receiver a good amplifier good cables and show us some price points.
I have been using my ears since the 80's when I buy cables, never thought about what you show us. Thank you for the insight and the enlightenment of speaker cables, Danny.
𝘾𝙖𝙗𝙡𝙚𝙨 𝘥𝘰 𝘮𝘢𝘵𝘵𝘦𝘳 𝙨𝙞𝙜𝙣𝙞𝙛𝙞𝙘𝙖𝙣𝙩𝙡𝙮. Bottom line; It's the undue 𝙚𝙢𝙥𝙝𝙖𝙨𝙞𝙨 on audiophile cabling that's ridiculous. Even if audio jewelry cabling worked as well as the most fervent proponents claim, that minutia pales in comparison to simple best practices wrt basic acoustic optimization steps. Cables do matter significantly, as without them the voltage drop is nearly insurmountable...
So to actually have this effect in practice, you will need a very, very powerful audio amplifier[1] that powers a coil and a silent speaker.[2][ (or you would hear that speaker). This coil has to end up somehow on top of you audio cable.[3] *Now why would you do that?* [1] Your audio cable has less windings than the coil that was connected to the tweeter. Probably one versus hundreds. This means that a much higher magnetic field is necessary for the same effect. Now you are already using a full power amplifier signal in the first coil here. So you need a much bigger coil and a much bigger amplifier to have the same effect on a cable of 1mm2 or thicker. [2] If that other speaker with other music or noise is not silent, you would hear that speaker instead of your tweeter in this experiment [3] The transfer diminishes _at least_ with the square of the distance
This is to illustrate the effects of fields in the same plane or crossed. See more on it here. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_rWLCSx0Zuw.html
@@dannyrichie9743 Again, the situation is different than the average home situation. In a venue, an old-style cut-off dimmer - the only option in the seventies and if you're low on budget - gives _a lot of interference._ Microphones are very sensitive for this and cables at line signal levels. You can easily single out mixers with bad output stages (not or not actually balanced) that are more sensitive for this interference if your multi-cable runs together with the dimmer cable for 10 meters. But this is all on signal level with relatively high impedance. A signal out is often a few to hundreds of ohms, which indeed causes it to be sensitive for parasitic capacity (for instance by shielding or putting it in a metal gutter) and reception of external signals. Using good balanced cables helps, but does not fix everything. However, I have _never_ experienced this problem with _speakers._ The impedances involved are simply too low and the power levels too high when compared to the interference. Naturally, I assume we are using modern voltage-source amplifiers and that we're using reasonable speaker cable (not shielded, just thick enough). I guess a valve amplifier with a relatively high output impedance might suffer from the interference. So again: what situation are you describing. If your listening room is a circus of light with old-style dimmers and old-style amplifiers and speakers and you keep al wires close together: YES, you have a problem. But why would you? As to the "sounding" of the cables: if two cables are perfect they should sound exactly the same. In repeated, double-blind tested circumstances. "Nor I tried this new cable" does not even come close. Of course, if you convince yourself this 100$/m cable sounds better: go for it. It _will_ sound better, because you expect it to sound better, because that is the way our brains work. And that is fine. You make someone a living and enjoy yourself. That is absolutely okay. Just stop pretending it is "science" or "truth".
@@TheEmmef I've had lots of people come over with the expectation and belief that all speaker cables sound the same only to have their belief systems completely flipped within a few seconds of listening. And the real truth is that the cables do indeed sound different, and some distinctly better than others.
@@dannyrichie9743 it can be that cables sound different, and you find one sounding better than another. However, if two perfect cables sound different, at least one of them is _not_ perfect. See below why. If you hook up two pretty decent cables: you won't notice if you really setup a good comparison. See below why. Does it matter? Hell no. If you find one cable sound "better" than another, at least one of them is imperfect. _Choose the one you like._ Apparently there are a lot of _really bad_ cables out there if you can hear the difference. That tells you something about the state of "high-end" audio. *Why perfect cables all sound the same* An ideal amplifier behaves as a voltage source that has _zero impedance,_ call it resistance if you like. Speakers are designed for a voltage source. To meet their design criteria, the speaker terminals should ideally be connected directly to the amplifier terminals, _as if there was no cable._ Naturally, no cable is impractical in many ways. So we use cables. It would be ideal if the cable behaves _as if it was not there._ Because then it does not change the sound in any way. Now, a second, different but also perfect cable, also does not change the sound. _The result is that two perfect cables sound _exactly the same._ It also means that if one cable sounds different than another: _at least one of them is not perfect._ You can debate which cable sounds "better", but that is subjective. Tube amplifiers sound "better" because the inaccuracy they introduce (from the back of my head: second-harmonic distortion) sounds "warm" in a beautiful way. They are by no means perfect, but definitely likeable! *How the human mind plays around with hearing* And you underestimate the effects your mind has on hearing, for examples expectations, what happened before or the weather. It really matters. However, if you perform a double-blind testing repetitively and in a relatively small amount of time, you will not find a difference with two different, but very good cables. No one does that, however, as such a setup requires quite some expertise. And experts that know how to do such things, know that if the impedance of the cable is, say, a factor of hundred lower than the speaker impedance: you won't need to do the experiment. Thick cables, not too close together and not too long helps. And from my experience in PA I know that those cable won't be picking up audible interference from even old dimmers.
Thank you for the advice. Because of the placement of my equipment i had about 1m length where the speaker cables were touching each other. I rearranged the layout to maximise the distance and also kept away from mains cables was surprised how much better the bass reproduction became.
Your channel its great. You open my eyes and teach me so much. Thank you for sharing teory and know how. You have made a huge contribution to my audio world. Salute you from Argentina!
It would be awesome for this time spent on "cables" to be spent on demos of the complete catalog you offer. Graphs etc prove parts and placement for sure, but ears are anecdotal transducers. To each their own.
Why don't you just get a really really good speaker and first wire it up with cheap speaker wire show and record it with a external mic and then go and use very top of the line speaker cable do the same .. yes RU-vid will compress the sound but both test will have the same compression so you will be able to hear the difference and for just to compere use a mid priced speaker cable up after the high end one and then let us hear the difference keeping in mint all three cables will have the same RU-vid compression so any differences will be heard
Well, I've never been able to hear any A/B difference through the RU-vids. If the RU-vid processes reduce the resolution below, or raise the noise floor above, what's needed to tell the difference, you won't hear it. But as an alternative, record the sound as a high-quality file (eg FLAC) and put it on a server somewhere for us to download and play?
@@osliverpool The RU-vid processes as you called them would change all three so there will be a difference to hear IE: thre cheap one should sound really crap the high end one should sound NOT as crap and mid price should be some ware in the middle ..Yes they may NOT sound as in real life but still a difference
@@Rob1972Gem Not in my experience, no - what appears to happen is it typically lowers the sound quality to below the threshold needed to hear the difference at all. There's an analogy I like to use... On my main music system I can hear the difference between MP3 and FLAC files. But on another system I listen to which has poorer resolving ability, I can't. It's not that I hear the differences less clearly on the poorer system, I just don't hear them at all. The noise floor is an important factor. Differences might be heard in the resolution of very low level signals - but if the noise floor is raised by the reproduction equipment to above those very low levels, you can't hear them.
You are going to judge 2 cables, played by a speaker, recorded by a microphone, compressed, trough another speaker? Do you know how different speakers sound in person than trough ANOTHER speaker? And you are thinking about cable comparison... Actually, Chesky have cable comparisson on some of his reference CDs, recorded with great mic
Lol, look at our affordable speaker cables...omg. 3 foot = rouglhy 1 meter. That makes about 40 dollars a meter. Meaning, if you need 3 meter per side, makes it 240 dollar. Then you are not ready, nonono, you must do the connections yourself. Bi-wiring, bi amping? Kajing, the doubler bonus , 480 dollars!. Can you define affordable ? Have cables here, pure copper, 8 dollar the meter x5 x2, at 80 dollars and i am king ;-) (thank god they not invented triple-amping/wiring....yet). But i must admit; if i bought these kind of fancy cables, with argb leds, jewelry patrons, twisted, etc.etc. i surely would take a extra meter and lay them IN FRONT of my stereo, with standoffs ofcourse. Look bro, aren't they gorgious to look at! And the sound! Amazing!
I believe that cables nowadays are pretty good even if you buy cheap speaker cable. You should have pretty good speakers before there is any point in spending a lot of money on cables. if you do not have good sound then it is not just a matter of changing the cord and then you have good sound. It is m uch else that has a much greater impact on the sound than speaker cables!
Many amplifier designs have bridged outputs, so the speaker wires have a balanced signal. Any induced interference is likely to cancel. And if interference does cause a problem, the voltage running through speakers will be magnitudes higher. The lower level-input cables are where you want to spend time and money to reduce interference since the signal amplitudes are lower. I don’t think we need to reinvent speaker wire.
What if the wires are insulated? I have made braided non braided. Could not hear a darn bit of difference. What about the cables in the speaker cabinet? Those should be braided also? Tried both. No difference...so back to my piont. If the wires are insulated does that not reject re re interference? Greatt video on showing how coil orientation matters
I had installing problems with a coil and capasitor in my speaker filter a big coil 2,7mh next to a 5,6uf cap practaly cap againsed the coil wires. So like you have tested with coil to coil. So I have placed a sheet of Mu metal between those. This is very well hearable woouw the highs are more loose standing. Differance is not tiny I just set power to my cold tubeamp and right away noticeable. Thanks I had never come to install a little sheet of 0,004" thick ( 0,1mm) i had some left over Mu metal for sheelding a turntable motor againsed hum. Cool stuff this topics and speakers cables react the same way like you said.
GR-Research. I think all you are measuring is differences in amplitude of the signal rather than differences in frequency response so the only differences the changes you make should produce are changes in volume.
Hahah that's funny! The high pass cell of any 2nd order crossover filter has an inductor in parallel with the tweeter. The same applies for the woofer, where in thic case the inductor is in series with the speaker, but the output impedance of the amp makes it like it was in parallel with it. The effect of induction on the inductors of the crossover filter are for sure orders of magnitude stronger than those in the speaker interconnects (you haven't proven it here, but take it for granted). This means that if there can be any audible affect of induced current in the speaker system (which there isn't, unless your system is next to an IMR scanning machine perhaps, LOL), is due to the induction picked up by the inductors in the crossover filter, and very much negligibly in comparison, to the induced current in teh speaker wires.
Ok,I got some information about inductors and the parts he used,yet I just never got anything about interconnects and what they do to MUSIC.For one thing,the average person does not take resources and set up a room to sit in one place,and listen to a few genres of recordings.People who have a life,have things to do,and unless you live alone,with no children,no spouse,your spaces have been allocated for other things.Next,we have to take into account the music sources,our power sources,and our overall budgets. I listen sometimes,I spin vinyl,I play CDs,I have specialty vinyl,and I have live instruments.Currently,I use my computers a LOT of hear music,because it's just not vital to turn on a whole sound system,to listen to RU-vid music.Add to that,MOST of the world listens to compressed formats,some use BEATS headphones and others like them,some use earbuds and smartphones/tablets.I went from studio monitors and my second set,and now I listen on computers and my soundbar connected to my 'smart' TV.My point is that in your house,you run things,and if it works for you,sounds better to you,to have Krell,Moon,Dalquist,MaIntosh,Sony.Realistic,Legacy,$400 inteconnects,$4000 speaker cables,then it is the best,that you care about. I used to attend clubs and have spun in clubs,and I have NEVER heard anyone complain about the strings on a bass,the speaker wires from one system to another,nor have anything else subjective.I think we know can agree on if a system sucks,sounding like mud,rumbling,buzzing,and annoying our ears.Now from this content though,I am still not sure what that experiment has to do about the difference between my Vampire Wires,and the custom Red cables I got near my house many years ago.I still do not know why my Mogami sounds a bit better than a Hosa,connected to my instruments.Last but not least,I live on Planet Earth, so I dare anyone to debate with me about some damn cables they are NOT paying for...Good luck with that...
This is part of a 26 page interview of the making of David Gilmour's Astoria recording studio. David and his team are among many other artists that have discovered that audio cables DO have an ability for their recordings to sound BETTER. And they strived to build the best studio they could. This is just an excerpt, but shows you how seriously legends like Gilmour and company take audio cable. So DJ Madrox, i guess according to you that if my ears are fooling me, well, David Gilmour and his studio team and Steve Hoffman (mastering legend) , Bob Ludwig etc etc have ears made cardboard as well????? You are way too funny..... here is the interview excerpt... "Absolutely - our one chance to get as good as we could. We underwent a testing program. We wanted to listen to every type of different connector we were going to use, every cable we were going to use and also pay attention to the physical aspects of the support of the all the equipment. All this stuff we had learned had basically come from the high-end hi-fi field, which we’d been trying out over the years and discovered a lot of that stuff made a difference. Some of it was just different; some of it was detrimental but some of it was an improvement. So we went though and we listened to a whole bunch of XLR connectors, we listened to 20 different audio cables, because I needed 23 kilometers of cable to make our own patch bay and rewire everything in the studio… all the outboard gear and the machinery. We listened to 20 different cables. We directionalized them all first, of course. Every cable sounds different in a different direction. It’s small, but it sounds different. And actually, the most amazing thing we discovered was when we listened to our technical earth cables, which we have going into copper rods in the riverbank. Our technical earth cables are just a heavy duty, high quality, regular, copper thick-sheathed cable. We’d been recommended to try this multi strand thinner cable, which had been woven like some of our audio cables. These are cables for electric? For earthing, woven to cross individual strands at 90 degrees to each other as much as possible to help eliminate RF etc. We listened to this, and we ran it straight out the door of the boat, over the bridge to the copper rods and we did an A-B and listened. Even the technical earth cable, you could clearly hear the difference from the original earth cable we were using. But even more surprisingly, we said for a laugh, let’s just turn the cable around the other way and see if we can hear any directional difference on the technical earth cable. And we couldn’t believe it, but we could. What was the difference that you heard? A difference in clarity, I suppose. "
Love your work Danny, you could talk to me all day about spectral decay and polly caps but my brain will not allow me to believe this speaker wire stuff.
@@edgar9651 Whats being demonstrated here is common crossover knowledge. It gets gets Danny point across... but speaker wire doesn't have such extreme coupling issues as two inductors in close proximity. Could easily be solved by pulling your zip cord apart so the conductors aren't in close parallel. Or just make speaker wire out of ethernet, much cheaper per foot.
@@iowaudioreviews Neither of those actions will improve the performance on the whole. The gauge and resulting conductance of ethernet wire is too low, though it could work well in some very low-current systems. Now, separating the conductors in lamp cord greatly increases inductance, greatly lowering high frequency response, and also by geometry greatly reduces both EM and RF common mode noise rejection. If you want to see how cheap wire can be well constructed for high currents, look at the ~$2/ft Wireworld cross section. Braiding, especially about central tube, is a really good method. Shunyata expands on that advantage with additional conductors in their fanciest cables. Now, one thing Danny doesn't mention here is how strand-to-strand conductance creates multiple modes of electron flow. That is mostly solved with correct counter-rotation of twisted, stranded conductor bundles. (P.S. Blue Jeans cables have this WRONG.) Hopefully he will address that and the obvious advantage of very low external B fields of ribbon inductors. The great Alex Gibson of FMS cables decades ago said to me: "Cables are 95% geometry and 5% materials."
I don't get it, Danny. Ray Kimber gets it. William Low gets it. You explained it very well. Now I get it; why not most of your audience? Your video today really helped me to understand inductance coupling - it's all about orientation. Easy to understand. That's all. Taking it down to four orientations and a simple white noise tone was brilliant. Big thanks. But why are so many comments revealing that you make no sense? I think that this was a simple exercise to understand but how can it go over so many heads? Ottawa, Canada. I think it's time to say goodbye to the flat.
The problem is, neither you, nor Danny got it. An Inductor is a very special device. In only works, if it is build like that. The wire has to be in very tight windings, you need that hole in the middle, and you need the right orientation. If you send electricity through the wire, the Inductor produces a very strong electro magnetic field through this hole. But it also works the other way around, if you send an electro magnetic field through the hole, it will produce a lot of electricity. With normal cables, this is different. They also have an electro magnetic field. But it is neglectable weak. Between two wires there is a pretty thick layer of isolation. The weak field doesn't even reach the other wire. And this is only the inductor. There is a big difference between an inductor an RF. RF reaches us with AVG of 0.2 mV/m. Your speaker wire has something around 50V depending on the power. Even if it is only 5V, it is 1/25000. 8 Ohm speakers are measured at 2.83V. RF is still 1/14000 of it. Yes, this exercise was very easy to understand. But it only showed that inductors are inductive. You really need to understand what you are doing when you want to transfer such results. Imagine you would like to know if your bicycle needs fuel. Just because your car needs some fuel, it doen't mean your bicycle needs some too just because both have weels.
The people 'getting it' simply don't know electronic engineering, all he did was an experiment Michael Faraday did around 1830. Ray Kimber is selling a product, I want DBT proof. Did you hear about the audio critics who were told expensive audio cable was chicken wire? A good portion of them said it sounded scratchy. Look up cognitive dissonance, psychologists have a field day with this nonsense.
@@Sqwan2 Okay Sqwan. Thanks for the info. But I would think Danny would understand what you are saying - that he has at least as much knowledge as you do. You may disagree. Also this is what Ray Kimber also talks about. Are you also in disagreement with him? Do you think these guys are just selling snake oil, then? How would, taking the devils advocate, an ordinary guy like me take your word over theirs? Just a question. They win awards for their work; have you designed better cables and crossovers? It's just a question of authority is all. No offense meant. It's just that one must be ready to share one's qualifications before they can be expected to be believed. Regarding the "thick layer of insulation" you speak of, where is this 'thick' insulation? My basic 12 GWA wire is 'insulated' in 1mm transparent rubber sleeve that is glued to another 1mm thick sleeve. Therefore I can see only 2mm of separation between the positive and negative wires by transparent rubber only. I don't think that's especially significant. Is it? But since they make it and every one buys it, I'm in the same boat. At least it's 12 guage, and that's all that matters. Right? As for you, you seem sure that you know what you are talking about. I'd appreciate any online link/article if you'd like to share, but it's not necessary. So, if I understand you, despite all that I've said; the interference is at such low levels as to be inaudible. So, would you have me ask, 'why all the fancy cable at high cost', even if it is basically Kimber Kable at a third the cost? Correct? I understood that Danny was using the inductors only as a teaching aid to help us understand that wire orientation (in braiding) is what matters. To me it seems more effective than the 2mm of rubber 'shielding'. So I understand that the counter-clockwise braiding helps to noticeably reduce interference. Are you in disagreement with this? Or is it more that you are in agreement technically, but it's too small to notice, and therefore not worth the investment? Therefore, in the final tally, do you see it mostly as a sales pitch? This is one of the major themes I've gathered in disagreement with Danny Richie.
@@mosfet500 Yeah, I agree that cognitive dissonance is powerful. I've studied enough philosophy to know that the human psyche today is rife with it. Opinions and speculations become fact. Some facts are fake and some are history. And then it's rewritten over and over and over again. And when 'new' facts arrive they are dismissed out of hand when they disagree with the prevailing winds. Forgetfulness is one way we deal with it. 'Science' is another. Indeed most people can be fooled most of the time. In the end, I guess you gotta get these speaker cables into your hand and do your own tests. And who would believe you if you did a video about it? Afterall, who are you gonna trust the most, mosfet500? (nice handle)
@@nickburak7518 I don't think that he has more or less knowledge as me. In building speaker he probably has more knowledge than me. In electrotechnical science maybe I have a bit more. But it doesn't matter. Even the best can be wrong. Look at Newton. You can apply most of his laws even though he was wrong about gravity. He is a big authority but when Einstein found out about special relativity, we had to discard some of Newtons ideas. And this is great in science. It doesn't matter who or what you are, if you have a reasonable doubte, it has to be considered. In case of Danny and Ray I assume, that they know exactly, that you cant measure any difference. Otherwise they wouldn't measure there speaker with cheap wire and croco clamps. And as they profit from selling this cable, they are not considered an authority anyways. As I said, autority is never an argument in science. Therefore, my qualification doesn't matter. You can look that up or you can try to measure it yourself. I bett, you will measure a lot less. Okay, the insulation part is a bit tricky. As I am not native english I might describe it wrong, but I will try it anyway. The electrical field is complicated because it is more like a direction. Therefore it is expressed as a direction vector pointing to the source. I indicate that as _>. Now, this is the formular: E_>(r_>) = ((Q/4Pi*Epsilon0*Epsilon_r)*(r_>/r^3)). So you see, E is a directional vector as indicted by _>. Fortunately we don't have to dig that deep. You see the (r_>/r^3) part? That means, that the distance reduces E by a power of 3. Considering, that Q is super low, because the inductance of a cable is so low, 2mm are miles. I know, this is super simplified and experts can argue with it. But for what youtune offers, this has to be enough. Of course I can share a link: en.wikipedia.org/wiki/Electric_field. And one for antenna basics: en.wikipedia.org/wiki/Open-circuit_voltage I don't know if it is inaudible. But it is unmeasurable if you have a shielded cable for 20 bucks (and probably also not with a normal transparend speaker cable if it isn't super thin and super long). I have also tried more expensive cable and for me it was not audible. With very cheap cable you can get issues. Why super cheap cable are questionable is described in the open circuit link. So, why are there these high cost cable? Because there a people who buy them. You can also ask, why is there a market for feng shui. Things dont get reasonable just because some offers it for a high price. Actually, if you look at a probability density function (PDF) and someone offers you something that it is of by sigma1, it is most likely not worth to buy it. There are exceptions but this is already expressed in the PDF. I don't disagree, that braiding improves the quality of a cable. I disagree, that you get a difference between a normal good cable (1000$). I personally doubt 150$ speaker cable, too. I agree, technically braiding makes a difference. For my ear, the difference isn't high enough. Also there is a difference between cheap cable and "good cable". But doubt that there is a difference between a good cable and 5000$ cable from kimber. I don't think that it is a sales pitch by Danny, but I think it is when it comes from kimber. I really think, that Danny belives in it. But I also think, that he absolutely knows, that you will not measure it no matter how hard you try, at least if the experiment fits the situation. So why is he promoting it anyway? I think it is psychological. If you buy something expensive, you feel great about it. So your brain inhances the sound even if it is the same sound as it was before. So it is absolutly okay to buy this cables. Studies have shown, that every one does that. If you would like to get into it, bounded rationality is a good point to start: en.wikipedia.org/wiki/Bounded_rationality. If you dig deeper, you will find several effects from that (e.g. anchorage effect, I have forgotten how the above mentioned effect is named [PS: as I see now, mosfet500 has named the effect. It is cognitive dissonance]). So, considering that I am not native english and that youtube isn't exactly the best plattform for scientific discussions, I hope I could build a good case anyways :D
Danny is illustrating *principles of magnetic induced interference* and even has an experiment set up to *empirically* show it with differences in measurements solely dependent on changes in physical orientation! (I wish he had had a second camera showing the coils used each time). Bottom line: *He shows you that the orientation in space of magnetic fields has an influence on induction in other conductors* Or didn't you get that? But you do know that a wire carrying current has a magnetic field, don't you? And that a wire in a magnetic field can have a current induced in it by variations in the field (or motion through it)? Then he shows us the speaker cable that has multiple conductors going in one direction and multiple conductors (to be used for the return current) crossing the first ones at near 90°. The whole point of doing this is to reduce the inductively induced current which would modify the current already passing through the cable. So what difference would you expect to hear in a cable that a) has almost no induced magnetic interference to one that does? I'll tell you what I expect (from experience, although I am also a physicist and engineering project manager). Very little induced interference: Deeper cleaner, punchier bass, clean midrange and unrestricted treble, freer, more impactful percussion. With induced interference: more 'constrained' sound, less transparency, less impactful percussive sounds. Would you have said "no difference"? There are of course many more factors - eg. in signal cables, conductor material (OFC, OHCC, silver, silver clad copper etc.) cable geometry, dielectric material (or air!), shielding or not, balanced or not etc. etc. In connected speaker cables there are also a host of other factors like amplifier behaviour, speaker impedance, imperviousness to RF (which may disturb the amplifier, even though you can't hear the actual RF) and much much more. *Their influence is miniscule alone, but they all accumulate* And here's the thing: let's say the main music signal is at 0dB. But the cues that our brain likes to "know" it sounds real (eg. concert hall echo for example) are at -60dB to -80dB compared with the instrument that caused it. That's a tiny tiny tiny signal. And guess what - music is not a sinewave, it's thousands of waves imposed on each other to get the complex waveforms needed for a single piano or violin - imagine what it needs for an orchestra, and how low level some of them are. And they are all *varying in intensity every 50 microseconds* (at 20 kHz). So can the induced current swamp some of these waves which we know are necessary for a completely faithful (high fidelity = hi-fi remember!) reproduction of sound? ABSOLUTELY! That's why we're so 'anal' about the clarity and fidelity of EACH and EVERY cable, whatever the type. Imagine you have a CD, a preamp, a power amp and some very revealing speakers. The cumulation of 'clouding' through poor interconnects from CD to preamp, from preamp to power amp and from poor speaker cables to speakers results in a duller, more lifeless sound than if each cable were perfect. I like the analogy of looking through glass windows for each cable in the system. If each of the windows is a little bit dirty and has a different coloration, then the end result will look quite different and duller than the scene you want to view. If each window is as clean as possible with as little coloration as possible, then the scene you want to view will look much more like what you know to be true. Wishing you lots of musical enjoyment along the way. All the best, Rob
Perfect illustration of what is happening would involve an oscilloscope. Science can not involve subjective evaluations because we know, and we have proof of it, that subjective evaluations are not dependent upon objective reality. Our ears, and our auditory system which receives the signals, is subject to its own kind of interference. An example from the world of taste rather than hearing was when the American Association of Wine Economists did an experiment with professional sommeliers while scanning their brains in an fMRI machine. They were able to see objective proof that when the sommeliers drank wine from a $300 bottle of wine, the pleasure centers of their brain lit up like a Christmas tree, and when they drank wine from a $5 bottle of wine, their brain showed very little activity. Their subjective evaluations of the two tastings matched, with them reporting the cheap wine was bitter and unpleasant, while the expensive wine was nuanced and flavorful, etc. Of course, the wine actually IN the bottles had been swapped without their knowledge. The sommeliers were NOT lying. The experiment proved, simply, that our subjective experience is not based primarily on the objective signals received from our sensory organs. It is based, largely, on context and expectation. That is why for science, you have to rely on objective testing tools like oscilloscopes.
Thank you for demonstrating why the positioning of inductors in a crossover construction is important. The cable issue is still more about psychoacoustics than science, but that arguement will rage until the end of time or for as long as companies make lots of money selling cables.
Nice to hear a compliment go to Danny. So far I've read far more "I don't believe you, Danny" comments than anything positive. But, what can be heard (a reduction in inductance coupling) is science. Maybe Danny cannot provide you with any more proof 'scientifically speaking', like as in numbers and formulas than this, but it's more than enough for me. I guess I'm the odd man out, but this is often the case with people who understand something that's different or difficult to understand.
@@nickburak7518 I may have complimented Danny on the stuff he does around crossover optomisation it adds value - the cable sounds "better" issue is all smoke and mirrors and adds nothing to his credibility.
At first this video seemed daunting when you started connecting all those connectors to the coils. But once you explained the polar regions and the directions of their electro magnetic fields, everything made sense. Ah ha moment.
So should all of the speaker cable in the cabinets from the terminals to crossovers, and crossover to the drivers need to be a heavy duty crossed wire speaker cable too? I haven't seen that in your speaker kits or crossover designs, so I'm curious why you don't use your expensive crossed speaker cables throughout your whole speaker build if parallel speaker wire is bad from the get go?
@@dannyrichie9743 Thank you, I actually did a little experiment and re routed my speaker cables away from some power cables from my subs and a power cable from the TV and the hiss at full volume with the sound muted went away. Most of the hiss came from the tweeter and it was audible when listening loudly. It doesn't look as nice seeing the cables out, but it was so worth the sound improvement in clarity, especially the center channel! My cables suck and are just normal 14awg with Media Bridge bananas, so they have no sheating or sheilding on the cables. Maybe try this experiment to see if you can replicate what I had going on, it was real and I am no audiophile by any means! Thank you for the tip, it worked for me perfectly 👌👍
@@biff196972 You are not alone. A LOT of people have experienced exactly what you just did. You should start a new post stating all of that and maybe some of these hard headed guys will realize this is a real issue and sometimes an easy fix.
