OMG If You Coil Your Speaker Cable You're Gonna Lose Fidelity?!? 

Finally, someone who is putting REAL SCIENCE behind speaker cables! Thankyou Audioholics!

Super looking forward to the next vid of measuring audio performance from different cables. Good stuff !

Thanks for talking some sense into me Gene. I was starting to get sucked in to all the fancy braided cables when I know better. My 12 gauge in wall cable is just fine.

More and more I find myself making the same statement to my audio buddies. Does it make a difference? Yes Can you measure the difference? Yes Can you hear those differences? Most likely not Do you want to spend money chasing that kind of difference? Most Likely Not

Thanks Gene, you are a real asset to us audioholics

Thank you for the true facts and going through the details in explaining how you came up with the results and if it will affect the sound quality. Your a true master Sr. Keep On Keeping On

I was recently wondering about exactly this, not just for speaker cables but for any cable. Thanks for doing the measurements and showing the calculations. Very helpful.

Exactly what I was looking for, on what to do about extra cable length , thank you Gene!

Enjoy your videos. You have great way of explaining the topics.

You should see my velcro-tied bundle of cables behind my setup. I haven't noticed a lick of difference in audio performance as opposed to having a rats' nest of wires.

Great video Gene thanks for quantifying it.

Thank you. Very informative and matter of fact delivery.

Thank You Sir. You are alway's so Informative and your straightforward way of conferring information is very refreshing!

Great video. I’m a avid music listener and your expert advice really helps.

Thanks for measuring that. I’ve always wondered if it made a difference. Now we know!

Great info as usual Gene

Thank you Audioholics. Awesome Channel

Nice video.. I always wondered if this was or was not a factor. Real world knowledge like this very useful. Thnx!

Awesome video!!!! I have speaker cable coiled to hide the extra and wondered about this. Thank you for sharing.

Thank you for another informative video!

Thank you for pointing out the coil effect for last 11 years i wondered if the extra 2 meters i have on all 4 back channels would cause any interference. It be nice to see you put big brand cables to the SWORD LOL.👏👏👏

great video. very useful info

Thanks. Great technical explanation. Erases any doubt.

Thank you, good to know and thanks for sharing, I have just moved house and need to set up my system again.

Thank you! I've been wondering about this for a long time... but was too lazy to do the measurements myself.

Nice to know that my thinking was actually correct!

Thank you for doing this Gene. I always tell people if you can hear it, you can measure it. Don't relay soley on listening tests, espeically if its someone else listening. And I am not saying different things can't sound different because sometimes they do. Just that if someone is claiming some crazy attribute about something and it can't be measured they are probably BSing you. And just because something measures or sounds different doesn't mean its bad. It all boils down to personal taste. I have some headphones that measure very flat or are on the Harmon target curve. I personally don't care for them. Its just not a sound "I" like. It might have to do with my tastes or my hearing. My old abused ears just don't hear flat anymore lol. I like that you did the test and proved it does actually effect it. Then you did the math to show HOW it effects it and where. You are right, most can't hear can't hear that high (if anyone). Heck I can't hear to 10K if that high. And when I do all I hear is hiss or noise anyway. I am actually more sensitive to bass. I can easily hear or feel down to 10 hertz. I remember years and ago a high shop let me take home and demo some high end cables once. When I brought them back he asked me what I thought. I told him I wasn't sure, maybe they were a bit better but it wasn't night and day. Certianly not enough to warrant the price of the cables. Especially on my relatively cheap audio system. I mean if I could afford and had a 10,000 dollar or up system then sure I guess I would do it. However when your entire system cost like 1500 to 2000 bucks expensive cables didn't make much sense to me. I will give them credit though they looked great and were really well made. And I think they were only like 1 or 2 hundred dollar cables not some of these stupid crazy expensive ones.

Good stuff Gene, could we see some tips on tidying cables in the back of audio racks/cabinets sometime? Like the average 4-5shelve units with multiple components and a myriad of wires!

Very interesting video

Thank you! Proper debunking!

Thank yu for very well done analysis

UR new house rocks man GLAD 4 U Man

Thank God that up. I was seriously worried that my coiled cables had beginnings of creating a black hole. Phew, I can rest in peace now :-)

Wow, I had this question after thinking about me and my dad making an electromagnet back when I was in fourth grade. I didn’t expect it to make a diff in sound, but thanks for the breakdown.

Great review, thank you! 👍This perfectly answers my question on whether I can buy similar lengths speaker wires and get any loss in sound quality since one speaker is 6 feet closer to receiver than another. I should see no audible difference.

Thank you for getting the truth out.

So not even if we had the hearing of a bottlenose dolphin or a bat... would coiling our cables make an audible difference! :) Thanks for the video Gene!

Thank you

Real engineering! Thank you!

Although I have no idea what you're talking about, your message is clear! Thanks for saving me $1,000's on my wire budget as I'm building my 2.0 system now.

I really like that you use science to differentiate between best practice, bull crap, and reality. At the end fo the day peopel spend a lot of time, energy, and money on things that in reality, don't improve, or degrade their experience, which is what it should be about, the experience and enjoyment of the hobby and content. I mean the producers of content, don't put as much effort in to signal integrity as some of these home listeners do. Overkill to a fault.

Appreciate your scientific knowledge

Nice video. I always knew this to be the fact (as an EE), but had never seen measurements and conclusions before. Very nice. I would like to see a review comparing balanced vs. unbalanced cables for sound quality. I don't think there should really be any difference for reasonable lengths.

very good

Oh my God, I love these thumbnails! pure #audioangst!!!

Just found you great info.

Great info 👍I did wonder 💭..

Gene and Amir shining a light on the murky home audio industry. Awesome work guys.

I love the shorter cables you can get from Monoprice. I bought a bag of 1 ft power cords for a decent price because my power strip runs right behind my gear, same with interconnects. Gets rid of a lot of "cable clutter "

Hi, Gene, Very interesting and well done work. As we can see, the increase in inductance, comparing a cable straight and the same cable coiled is minimal: 2.36uH to 2.56uH. It could be also interesting to compare the cable capacitance in the same both conditions (straight cable and coiled cable). Regards.

Thank you 👏👏👏

me liking this engineering measurement of audio-related gears and components...

fantabulous

"wayne kerr" lol, there are lots of "wayne kerrs" in the audiophile world

Love that you're a Grogu/Mando fan. Raises the status of your site to 11!!!

How about do some measurements of the effect of having power cables next to audio cables? Balanced and unbalanced. Thanks!

Hi Gene -- your blogs are fantastic. Would you consider doing a review of portable audio players as these things are swimming in gallons of snake oil.

I connect my spkrs with twine, sounds great!!!

I love your utube videos!!! So much info.but my question is can you cover the best speaker cable type for electrostatic speakers, I have a pair of vintage Acoustats 6600, someone told me that Neotech Cable -Nemos 3080 is the best. They said it is a occ cable? Do you know anything that is not overly expensive. Thank you

Wayne Kerr? Hahaha. What a great name. He needs to meet my friend, Jack Mehoff.

Agreed. it has very little affect because the load is so strong, or low impedance 8 or 4 ohm. Do the same measurement on a low line level signal between something with 1v line level RCAs, then coil it and connect it to a high impedance input - something with like 10k ohm input, or even better, into a phone pre-amp.

Hey Gene would it be possible to make a video about good quality affordable component racks?

I'm pretty sure Danny Richie invented the Wayn Kerr meter. It's named after him.

you and your measurements ! How am i gonna sell special magic wooden cable risers ?

Many thanks for your very professional investigation and presentation! As an engineer I totally agree with your findings! It is always important to judge the relevance of values and you really showed the facts with your test and calculations. Impressive!

Thanks for videos.. I want to add an amp to my av receiver but not enough preouts have you used or recommend russound 1.2 adp speaker level to line level adapter...or do you have any other recommendations

Danny will have a fit... 😆

What do you think of Ehtan Weiner's Null Tester? Can you / will you get one?

Capacitance of long speaker cables is much more of a stability issue in amplifier design. We add a inductor of 0.8 to 1.2 uH internal to the Amp. Extra inductance formed by a small length of speaker cables coiled under your couch might actually not be too bad a thing.

And not to mention, that was the entire 20ft coiled when you tested it. so yeah, coiling a few extra feet matter not. great video.

Would there be any chance of a video ,about what are the effects of having power cable in coil, compared to figure 8.

Hi Jean does having speakers in a set up of difrent ohms adds any difficulty in setting up your system ?

Thanks Gene, Just a bit of study in regards to inductance and capacitance and working with the math involved. Would give people a much better idea about how things can be orders of magnitude to small to hear.

It's great that you can give the details of these components that are part of systems. However, as the whole purpose of each system is to deliver sound to the listener's position in space, shouldn't you be measuring the differences to that, when you make changes to the type/length/connectors/topology etc. of speaker and interconnect cables?

I once put a pair of bookshelves right next to my amplifier, coiled up the excess wire and stuffed it into the port of the speaker, well the tweeters melted from parasitic oscillation in the feedback of the wire picking up the driver's emited EMi. You may want to add a word of caution on where these coils are placed. A little bundle right next to the speaker is in my experience an absolutely catastrophic mistake. I feel EMi is highly underestimated, especially around single ended RCA interconnects, I'm pursuing braided power cables and toroidal power supplies for that very reason. But just interpreting the "inverse square law" with enough sense to not stuff wires inside your speakers is probably enough to avoid a meltdown ;P

Dude congratulations! You should do a different speaker cable every week and build out a database! It, sounds to me like an ideal speaker cable would be one with enough inductance to roll off all the noise above 20k what choo think about that? I think it's that much less flux in the tweeter affecting field stability. The energy levels may be small, but add them up like the "Ultraviolet Catastrophy" and the energy across such a broad range of frequencies may be of some subtle significance.

Hi, does ferrite cores on RCA audio interconnect cables affect sound quality? Thanks.

This subject has been haunting a good portion of viewers and I do remember the conversation I had with salesmen giving me that very faulty information; at the time of this "Inception", I was young and very naive.

Please do pwr cables mixed with speaker cables and/or RCA cables? Like everyone else, i separate them. Its a massive hassle though. If it doesnt make a difference it will make a huge difference to my cable management

lol mine have been coiled for years and I still use them without any issues!

Technically the coil for twisted pair has little effect except the cable is too long with the extra length adding more resistance due to more length, more capacitance due to more length, and more inductance due to more length. Resistance, inductance, and capacitance are all per foot or per unit of length properties of any cable. For test equipment, consider adding a TDR to your tool kit as it can be used to measure the nominal impedance of cable as well as length if the dielectric is known or dielectric constant if the length is known. If your speaker cables were two single conductor wires and you coiled them each by themselves, the yes, you make a solenoid cable. However if you coil a braided, or twisted pair cable, you again have an inductor, but in a configuration known as a Bifilar Coil. The inductance reacts to common mode current on the cable, not the differential mode signal to the speaker. See Bifilar Coil for more information.

do you guys have any updates on the yamaha avantage series for 2021 i want a new receiver but looks like onkyo is out of business

Gene, I know you don't like these cable questions. But, when I look at your charts, the Kimber 8TC and 4TC seem to perform better and flatter across frequencies than all the others. Am I reading this right? I'm thinking the others will actually cause rolloff above 5 or 10khz. Did I read it right?

Gene my friend! You're the new "Cable Guy" but obviously not, Jim Carrey. Lol 😆. Anyways cool video. Knock! Knock! Knock! Its the Cable Guy! 😂 Crazy film that Gene. If you haven't seen it, watch it. Its funny!

Can try to measure CAT7 LAN cable compared with normal speaker whether any significant difference

Does difference in speaker cable lengte have an influence. For example left channel 2,5 meter and right channel 5 meter? Or better keep them the same and coil the left chanel cable lenght?

MS Natural Keyboard 4000... love them, but so hard to get.

My speaker cables has over 80" left-over because I move from a bigger room to a smaller, coiled behind the AVR, bothers me should I cut it? with a few slack to avoid tension. Thanks Gene for put the time on look into this subject.

Did you test the cables with real high current swings? as it is during music playing? The difference will be clear during heavy loads and load swings.

I love the fact that you science.

I always thought it was about interference. Is there a measurement for that?

This is the reason I have yet to do cable management behind my rack ;). It's a MESS!!

Did you go with a right-hand coil or a left-hand coil?

I enjoy watching your informative videos Jean. Keep up the good work. You are a blessing to the audio community.

Hey Gene, as an electrician who has done well over 500 RJ45 ends (CAT 5/6/7). I watch videos of people saying we need to maintain the twist as much as possible into the RJ45. I think it’s hog wash because what is 1 to 3 mm going to make in the long run of a cable, that could be as much as 100 meters? Especially inside the devices the cable is plugged into. When the traces on the board travel several inches to the microchip for processing. I know this video dealt with speaker cables. But CAT 5/6/7 are also a big part of the HT industry, as you know. With that said, and with the equipment you have. Can you do a test on a CAT5/6/7? Where one cable has the wires straight inside the RJ45 and an other where they are twisted until the very end? Keeping in mind the frequency the cables are used at as well.

Gene always trolling lol

What do you think of GR Audio perspective on cables

Is that excel sheet located somewhere on your website or only available for your patrons?

Is there a way to measure RFI on cables? I have a couple of cheap radios with a length of thin cable which picks up the radio frequency waves. Unless someone convinces me otherwise I'm sure all cables in AV are to some extent acting as aerials and degrading sound.

Looking behind my theater components you would think that I could control the Luna lander and the Mars probe. Thankfully I paid enough for my tree trunk power cable though, 😉so at least I can sleep at night. My question is this: how many patents have been issued to these cable and cord manufacturers?
