Powercords - $40,000 Versus $40. Here's My Opinion! 

Brand new wireless Lavalier. I hope you all don't complain anymore 😂

I call BS. Power cords don't "settle or cook in". The physics of the electrons in electricity don't change, nor does the physics of the wiring. When it's plugged in, its energized and electrons flow. Go ahead and A - B them immediately. If you have terrible power to your home (noise or fluctuations), a 4' cable won't magically fix it. Would these cables change the sound if your system was running at the power plant, running off the source? Change the sound of your system with your home outlets delivering 105 volts coming from them? Have you replaced all the 12 - 14 gauge wiring in your home to something twice, three times as large? Here's a GREAT video for you to do. Bring in ten people, do a cable comparison of all your different cables, and see if anyone can hear which cable is the Amazon or stock cable. Don't worry about "cooking" them in, because they'd all have the same conditions for the test, and it doesn't matter anyway. Ten cables with one would being the cheap one. See how many people can determine which is the cheap power cable. That would be must see TV.

I would love to know the manufacturing cost of a 12,000.00 power cord.

Power cords a ALL rely on the same Romex in the walls, and have the same results. The fact people spend more and think the sound changes is absurd and not supported by science. What happens IN the amp is far more important. Same with speaker cables. A lot of snake oil out there.

Anyone who thinks 7ft of 40k power cord at the end of 2 miles of cheap utility wires is going to make any difference is seriously living in never-never land and doesn't know the first thing about electricity or electrical engineering 🤣🤣

"$40,000 dollars worth of powercords" should never be a part of anyone's vocabulary unless they work in a powercord factory

This is absolutely waste of time. There are no objective measurements and your assessment is totally flawed. The human ear is the worst measurement tool there is. It's inherently flawed and no way around that. Power Cords are just a another profit center for the gullible audio buyer. That simple, at most the are audio jewelry. These have been proven again and again that they don't make any improvements.

Other than larger diameter cable these fancy cables are all bunk imo. SHOW ME 1 MEASUREMENT where these power cables compared to a conventional heavy gauge power cable improves something!! You won't be able to do it. The wall power typically runs into the primary of a transformer, there is no impedance matching. Everyone seems ignorant of the fact that power is running through shit 2 conductor cable from the breaker box to the outlet. Interconnect cables aren't much different in this regard but they do influence the sound if they are sub-par.

Please youtube take this mans channell away from him. watched 22 min and got 1 min of actual info. never again. I guess he likes to here himself talk

$40,000 for a power cord, I would like to think your subscribers are not that stupid!☹️

The sad thing is that you actually seem to believe this nonsense 🤦‍♂

Every electronis has a power supply board that is responsible for the clean power no need spacial power cord!

I’m guessing Shunyata Everest, just based on my own experience. It was a game changer in my system, leading to a full loom of Shunyata Omega, Sigma, and Delta V2 power chords.

You should take Gene’s challenge over at Audioholics, and prove to him that your ultra expensive “snake oil” cables really do work. I tend to agree with a skilled, and experienced electrical engineer would know how to judge the difference between $200 cables, and $40,000 cables. He has the instruments to do the measurements. Get together with him on a video, and let’s see some proof (or lack of proof) that there is a provable difference (either electrically, or audibly). I hate to see people wasting money on snake oil when that money could feed a family of four for three years.

Blind tests just completed on a $380000 system over 6 days. 100% of people COULD NOT pick between a $8.00 chinese powercord, and a $6600 Gryphon powercord.... tested on 14 people, both audiophile and novice. Tested on varying styles of music, at various levels of volume. Tested at 22 degrees Celsius. Both cords had been run in for over a week, (30 hours listening)

So your entire house is wired with normal wires but the power cord that comes from your wall - that one needs to be 40k. Would love to see the science on that.

You are doing the right thing, comparing gear that most people don’t. Love your channel, keep going mate 👍👌🎼🎼🎼

Is there a $6,800 difference in sound between the expensive cord vs thick standard one? Hell no. My server powercords have to supply up to 30 amps with ease, they cost 10 bucks each and easily provide all the clean power my equipment needs.

Torus

I think the ultra hi end stuff probably has a power supply that’s not as susceptible to cable variants as lower price components. I have a modest system and cabling makes a difference.

I'm with you, and I think that power cables make a difference. But in my opinion you are better off getting less expensive cords and putting the money into EQ'ing your room properly. I know that this sounds like some hometheater talk but, the interaction of your speakers with the room makes a huge difference. For years I ran my hifi rig with just room panels and other things you can do to help. BUT, unless you have the perfect build size room along with treatments, you are never going to get you rig to sound balanced. Every room has peaks and nulls and unless you measure your room and you compensate for the peaks and nulls you are never going to get your rig to sound balanced. Sorry but that's just the way it is. I recently removed my DAC/Preamp "very well regarded by the way" and installed a different one. One that includes room correction built in. WIth that, I was able to find that my room had a 12db peak at 70hz and a dip somewhere around 120hz. The preamp allowed me to correct for that "to a point" and the sound is the most clear and satisfying bass I have heard on my rig. I have gone through power cables and with some I was able to hear the differences they made in my rig but what properly calibrating your rig to the room can do is much more than any cable can do. I recommend people focus and spend their money and energy into EQ'ing your rig to your room. The gains very significant.

In a blind test no one could tell one power cord from another. I guarantee it!

“High end” power cords are ridiculous. Plug in 1 meter of wondercable when the rest after the socket is stock standard home electric cord. If anyone can provide scientific evidence it does affect the sound I will eat my shoe.

I agree that cables and power cords matter, but they do not have to be expensive. The wires in the walls and outlets matter too, but they do not need to be expensive either. Good quality, commercial/industrial grade wires chosen carefully can be as good or better than fancy audiophile products, and they can save the hobbyist a lot of money.

Amplifier plugged into wall socket with russ Andrews Mini Purifier SuperClamp beside it ,everything else plugged in AudioQuest niagara 1200 or russ Andrews X Block.The Mini Purifier SuperClamp will sort the noise like fridge lamps computers on the power line.

Nice one Jay. I think this is your best vid so far. Thanks for putting some very sensible perspective on a (potentially) contentious subject. A good system is something to enjoy not obsess down a rabbit hole-where you can't hear the music anymore.

Jay I think you should go and look at your 3050 internal ; if you look at the wiring to and from the boulder 3050 transformers, there is no magic super cable, it’s just plain old wire, the idea that this has no effect but your power cord does, is just magic thinking

Had enough after 4:09,, sick of hearing how much everything cost, how much is your system worth again,, 😴

What I'm trying to figure out is why a company would make a 20-100k amp, and then ship it with a normal UL rated power cable if it made their equipment sound crappy? Can someone explain why they would do that?

Awful…wasted 20mins of my life

I build speaker crossovers for my speakers and use alligator leads to experiment with crossover components. But when I had completed the crossover build (without the alligator leads) the crossover sounded different! So much so that I had to change some components. Cables do make a difference. The (cheap) alligator leads are made of iron, not copper and I think that is the problem.

The power from the home breaker box to the outlet, continuing on to the electronic component, can be no better than the weakest link. That weakest link is probably the wire from the home breaker box to the wall outlet. I don't know about a $9.99 power cord from Amazon, but a high quality 14 gauge power cable should work fine from the wall outlet to the electronic component. Obviously, adding a power conditioner also helps, but no reason to go overboard on that either.

nobody should condone that kind of power cord behavior its reckless , you don't need to do a video on 9.99 cords vs 40k how about very decent 10/12guage good quality cords vs 40k and double blind test them. Pure snake oil . and whats in the wall going to your panel better yet from the weathered on your house to the power company its not even Copper the lunacy about power cables but you want to be that guy , If you want to regenerate your power and then use a cord Fine maybe then but not even.

The key is not to decide based upon price, you need to decide based upon performance. If they don’t make a difference in YOUR system, they are a waste of money no matter what ANYONE says. If they DO, only YOU can decide if the improvement is worthwhile. It’s all your personal call.

It's always great when someone has the courage to speak their mind and not just go with the flow, but what you do which that challenges group think. I am extremely happy for what you bring to us in your channel! I agree with everything you said in this video. I would also add that many times when comparisons are being made we sometimes are focused too much on something and it takes several days of listening to truly appreciate what a product has to offer as a whole. For example, I just did a interconnect compare and was focused on the high frequencies only, after several days of different sessions of listening I arrived at different decision on what was best, because I listened holistically to the sound, not just the high frequencies.

Most good amp manufacturers recommend just using the supplied power cable. If I had the cash to burn I would also spend 200 k just on cables as well those fancy power cables are hard to stay plugged in . There’s no question that you took this hobby into the next level.great video.

It's interesting and yet too bad that the microphone 🎤 doesn't adequately show the differences in the bass region. I remember that one of the most awesome experiences happened with my system 25 years ago when I replaced 2 stock power chords with upgraded with ones I made out of Audioquest midnight speaker cables. The bass took on a whole other level. Apparently, the ear and body is quite a bit more sensitive to change than the microphone for bass.

Perfect timing for me since I'm getting ready to buy power cables. I'm not going to use the stock power cables but I'm not going to invest a fortune in cables either. I think for under $500/Cable I can get a nice cable that will do the job.

I own Venom 10 and 12 power cords Venom 8 Power distribution with the Defender protection all from Shunyata. Very pleased.

Firm believer in power cords here. Yes, power cords can make or break a system. I have proved it to myself over and over. Power cords will enhance a system but will not fix a crappy system.

Here's my opinion: Even if a power cord can actually make an audible difference, for the BETTER, in a system, which I do believe is POSSIBLE, based on what you are using as your starting point, certainly there is no doubt that when people start trying to tell you that these power cords should cost thousands of dollars, then you are now in the world of hype-based pricing. Take the absolute most expensive cord to manufacture, and analyze it. Yes there are ways to construct a cable that makes the raw cable construction itself much more expensive than standard cables, using exotic construction techniques, Litz wire, (individually insulated strands in the conductors), custom configurations of conductors, insulators, spacers, fancy jackets, braided/non-braided, and foil shields, complex and time consuming ways of terminating them with exotic, special, custom made connectors and plugs, etc....all this can add significantly to the cost of a cable, even more so if you start dealing with precious metal conductors. But a 40,000 dollar cable is probably giving the manufacturer and dealer about 38,000 dollars worth of profit to share between them. If not more. The hype is not the cable....it's the price. Yes, I do believe that cables CAN matter, but when it comes to power cords, if the last six feet of power cable makes a difference after the electrical power made it hundreds of miles through innumerable industrial grade splices, transformers, taps, substations, etc, and then hits the last hundred feet of romex from your power box to your audio room, then something is less than optimal about the power supply of your equipment, as that power cord is doing a line filtering function that should be handled ideally by a WELL designed power supply. The better the power supply the more immune to power cable differences it SHOULD be. So long as the cable gauge is sufficient, of course.

Placebo effect 🤣🤣🤣

Last 6 ft of power cable will "treat", "correct" "filter" ???? 17.15 No sir, they won't. If they can do anything, they could possibly prevent aditional noise from surrounding gear around that cable. You and all power cable beleiveres want to convice us how power cables actually have influence as equalizer of some sort. Again sir, no they don't. Only poorly ingeneered cable can make system perform diferently changing performace in negative way than how they perform with factory provided cable. Saying that I can't imagine that any manufacturer would put on the market their product with power cable that makes their product perform worse than it is designed for. Thy conduct numerous testings before release their (pre)amps or whatever to be produced. So far I never find recommendation from those manufacturers for power cable change. If there is any, that would be stupid. Why? Because I, as a buyer who pays for example 10K$ for something would legitimately ask why such cable wasn't provided by manufacturer for that price. I hope those who are using their grey brain cells can see absurdity of that situation! P.S. The reason why you have all those cables is actually fact you have nothing better to do and you can afford to have all of them at once. Sorry! You are big kid with toys that other kids don't have and you enjoy playing with them wich is acctualy nice. But facts are facts. All the best! Enjoy your hobby!

I don`t use the factory AC plugs. I buy ones for $75 on sale. I don`t know if they sound better, I use AudioQuest cables. I don`t spend huge amounts of money on them. $1,000 to $2,000 is insane. PS audio makes great AC conditioners for thousands, there`s no science to any of this

Jay, im new to your channel and absolutely love it. My budget is mid hi-fi, but ive had some great gear. I appreciate living vicariously through your vids. Thank you! 😂

Snake oil at is best

I highly suspect that the weak link of many systems is the computer connected to the DAC. Most PCs have horrible digital output quality.

Are these cords the main electrical wire, or the speaker wires? If its the power wire ,it couldn't matter much because of the hard wire in the structure. Speaker wire should be 12 gauge at the minimum. Any thing smaller wont allow the proper current to pass thru. 12 gauge minimum. I used 14 guage for a while, bought some oxygen free ,12 guage, copper , aint lookin back. I like what you do. Keep up the great work ,Jay!! All stranded wire, not solid. So i guess that the big money cords ise a heavier gauge wire inside. Which allows the ac a more open road to travel. That would make a difference.

I hold a PHD in EE and imo this is absolutely, verifiable BS. If anything these "advanced " cors ADD induction and capacitance. As long as you have heavy Guage cable sufficient to carry current you are fine. You DO NOT want to ",tune" with a damn cord. It's all placebo effect.Proper Power conditioning? Yes, power cord? Hell no. Stranded 12 or 10 Guage is more than sufficient for even the most demanding systems. AC "resistance" is negligible in stranded vs. solid core. Shake oil city. To clarify this is not a bash on your review but a slight on the marketing of absolute junk or devices that affect signals in the mhz range but claiming applications below 20 kz.

I just changed out my Prima Luna Dac for the DCS Bartok. Before I had through Roon wifi on computer to Apple tablet. I had ethernet hard wired from main cable router. So far I like the Bartok extra detail but it's not dialed in yet. With Prima Luna the singer was more upfront and cymbals in the background. With Bartok I find the cymbals to forward in the staging and singer too far back. I read a bunch of modes on the Bartok to adjust voltage and the phasing and settings. My guy was out of town that helps listen and adjust after install but will come by my place in May to help dial it in. The audio place I use has the main installers put gear in and do small test and then more experienced sales person comes by to dial in.

This guy keeps repeating the prices of the cables and money money money. That’s not the point. A good 500$ power chord with good conductors and shielding is all you need. Anything above that is marketing and tricking ppl to spend money

Again I gotta say, cables that carry audio signal can have some effect on sound, tho there have been tests done that show they don't, I'm still not shure on this one, but power cords do nothing but get the power at the wall to the equip. No audio signal, Either they get the power there or they're defective. Whether a stock cord, a twisted, a braided, the raw power at the end of the cord is the same, the same! It's like the mis-conceptions of a dedicated circuit, They don't isolate you from noise in your house electrical system, They allow you full current capacity. Most peoples houses share a utility transformer with up to 10 other houses so noise generated by a house several doors away is on YOUR system. People don't understand how electricity works, or the power supply in the gear. I've been doing electronics, electrical work, audio stuff for 50 yrs. I've never seen people like in the audio world that so deny science and spend money on placebo and are happy to be fooled, boggles my mind. I love tinkering with my system too but there comes a point where you gotta go WAIT this don't make sense.

I already made a comment but after the video I wish to make another one. People need humility. How dare people talk shit to you since you have one of the top 1% of set ups around. I’m sure the ones who critique or dismiss things as snake oil generally are the same kinda of people who argue politics on Facebook. Who has time for that? Keep doing you brother. We follow you because we understand you and most of us, myself especially, think you are one of the most honest guys in the audio business. One day I’ll email you and get some paid advice but for now I’m waiting to finish a few things. When it comes to fine tuning I’m gonna hit you up for sure. Cheers from Italy 🇮🇹

Did he say a $500000. System..😮 My hearing aids only cost me $50 My hearing aid charging cable was $5 And Im being honest with you..🙏

My whole system is about $7,000 so I can't really justify spending thousands on these power cords. All these cable videos show what these thousands of dollar cables can do for your system. Well, what about a few hundred dollar power cord for a more moderately priced system. Will I hear the difference.

Power chords don’t change sound. You would need to change the wiring in your house and drop feed to your house. What does work is a constant voltage power conditioner. As far as cables. They are passive devices. What counts is proper shielding and low capacitance. I’ve been through it all. Don’t waste your money.

Companies that make expensive stuff will not be very happy with you if you make IDIOTS think!!!

Thank you for all these videos! All I have to say is you don't have to have a million dollar system to enjoy music... But I really appreciate what you do in us allowing access to products that some of us will probably never have the opportunity to have! What I find unfortunate with some people is that they spend more time listening to their systems than listening to the music itself... Maybe that's why some people in the presence of live performance, seem to find it doesn't sound right... That's why I really wonder if their systems are really high fidelity or just that they fashioned it to their tastes... I presume that there will be as many good systems as there are pairs of ears to listen to them! Thanks again for your good work!

Watching this reminds me of a dark hole i been myself couple years ago , nothing wrong with better cables in higher end audio problem is higher end audio makes u do that and there is 50 levels of just that can make u go crazy u are listening to cables music just becomes a test run for you equipment , i start my audio hobby with vintage i was happy until my friend keep telling me about modern audio did that for probably for 8 years constantly keep swamping things , cables , power , Dacs u name it , about 2 motnths ago i just sold everything purchase my self i nice vintage sansui gear , Carvin vegas d38 speakers with 15 inch woofers , using non expensive wires like blue jean rca , and im the ost happy man ever this equipment simply dont care about power issues or quality of your rca its all natural sounding but more on tube side because sansui , i can easly say its first time in 8 years i get to enjoy all music from shitty old metal recordings to new stuff i dont have to Chace high quality only sources because my system is to reviling , im not saying new stuff is bad but im happy i quit Chasing the better sound

There is absolutely NO WAY that someone can hear a radio station from dirty power. Sorry it's impossible! They may hear a radio station but it's coming into their preamps due to no input shorting strips on the UNUSED inputs. Either that or they have shit interconnects that are allowing it to ride on the wire.

These expensive power cords are all bullshit.If there was an argument for them making any difference at all you would have to get rid of the so called weak link which is from the wall plug to your fuse board.The only time you would need anything of heavier gauge would be if your amps were going to draw huge amounts of current beyond what is capable from a standard cord.

I believe in a lot but not cables that change the sound and a good 40$ cable will sound the same as a 1000$ cable. it only transfer sound through copper that is it. So how does your cable sound warmer or more bass or more highs what causes that cause don't believe in it at all and just snake oil and you wanna hear a difference.

I think there are at least 3 factors which make power cables matter; vibrations, interferences and electromagnetic wave interaction with power supply.

I used the power cables that came in the box. So I can’t tell the difference, but if I had the money to upgrade to better cables then I’ll add new ones😂😂😂😂😂😂😂😂😂😂

I will sell you some special power cord lubricant. It is 100 percent natural. Extracted from the rare south eastern diamondback snake.

Do you have any idea how people are able to hear small differences after three days of breaking in? 1:100.000 I think.

Personally I found no difference in AC cable for my gryphon Diablo 300. On the other hand, my streamer is totally opposite. I tried 8 cables on the streamer and every cable clearly change the sounds. Its like I have change equipment brands. It’s not all about the cable but also the quality of the equipment. Just like Taiko didn’t matter when plugged in to the MSB dac. It all depends…

Great Video Jay. I must say allot of the high end power cords are way to heavy to allow a sound electrical connection to the IEC input plug these IEC plugs were never designed to have such heavy cables plugged into them. The weight of these types of power cables will pull the cable down at an angle partly reducing the contact with the IEC electrical pin and so worsening the connection. Also the IEC plug maybe PCB mounted within the component this again will stress the connections between the IEC socket and the PCB and again worsening the connection. I believe Furutech have a range of products to help support the weight of the these cables and plugs to help maintain a better connection. I certainly believe good quality power cables make an audible difference to a well put together audio rig but I also like to see how far you can strip it back and maintain a good soundstage so swapping out a $6k power cord for a $10 power cord on all components is fully stripped back and as you have found your audio rig still sounded very good :) Don't forget a well engineered audio component will take the AC line in at mains voltage and filter it using a high quality mains filter to screen out RF & high frequency noise. The filtered AC voltage will then be reduced to say 12-24volts using a high quality step down toroidal transformer and then convert this lower AC voltage to DC using high quality fast diodes before applying a huge amount of secondary filtering using good quality capacitors. This lower DC voltage will then be regulated maybe up to 3 times before its allowed to enter the sensitive parts of the analogue audio chain this whole process is commonly called a linear power supply. This low voltage heavily regulated DC power supply looks nothing like your AC electrical supply entering your House if you were to analyze this DC supply on scope it would be be ruler flat like a straight line not wavey like an AC sine wave. My advise is don't waste your money on hugely expensive power cords put your Money into well engineered audio components with well engineered built in power supplies using high quality components with lots of regulation and capacitor reserves this will have a far greater positive effect on your audio signal than any power cord on planet Earth regardless of materials used, design and price.

Funny, you invented a “blind test” that makes it impossible to blind test. Buying a cable in the 40k range is insanity.

If you spent 12K on a fancy power chord I feel for you. It does nothing and you are never ever going to find what you are looking for.

Who won. The company and seller of a $40000 power wire. Ahahahahaha. Ridiculous!!!

I always listen to RU-vid through my 1985 Sony Trinitron ( set on channel 3) and the radio directly through the wall power outlets - AM only. You know how much money I've saved in components!?

I use some nice Shunyata v2 A/C cords on my Focal/Parasound/Mola Mola setup. It’s not necessary to get good sound, as you proved. However, I do find that it makes a significant difference.

I manufactured my own, high spec. 6 x 1.5 m. power chords for around €600 .

I think if you did a double blind test you couldn't tell the difference. I dare you to prove me wrong

The power answer is have a dedicated line put in by your electric company.

Signal cables some diff., power cords watch- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HkmwcPdTlWM.html

If the difference was real and not the placebo effect, you'd be able to clearly measure the differences with numerous audio analyzers and measuring devices. It's science 🤷

we should make a solar set up for hi fi/clean and quiet

Can't wait to know what this product is Jay I'm very excited about this one.

There go retirement funds and dreams for many cable snake oil pushers...

Aww but your wrong Jay! According to Amir with Audio Science Review and Gene with Audioholics they all measure the same and even sometimes the stock power cords, speaker cables, USB cables measure better then aftermarket hi end power cables, and they all sound the same "Snake Oil" and your crazy with a medical problem called Placebo effect. Especially when you half to burn them inn LOL LOL I'm sorry, I don't know why they can't understand there is a difference, I guess they don't understand ultra HiFi

Jay, have you ever tried making or have made for you a power cable that uses the same wire that's in your walls? Just wondering. Did you try switching the cables in only one unit at a time to see in which unit a change made the greatest difference?

100% agree with everything you're saying here, which I've learned over the last 45 years. Continually learning still!

Sorry! But when will you be revealing this “new marvel of equipment” you were spoken about at the end of this video ? Can’t wait anymore as I am working on building my new listening room ! Thanks for your reply and keep up the good work !

Lot's of things can be wrong with the power even though the frequency, voltage and amperage are all within accepted spec. There can be lots of noise. Utilities routinely use the local distribution system as a communications system. The transformers filter out most of it, but it is still there. You may have reactive power issues. Utilities are constantly fighting VARS with cap bank controllers. The reactive power will impact performance of your power supply. Makes sense that a power regenerator like PS Audio's power plant can make a difference. In the early days of data centers we had to use local motor generators to get power clean enough to keep mainframe farms working reliably. You literally used an electric motor to spin a generator to get the system divorced from the noisy grid. What I cannot understand is how a short power cord can make so much difference after miles of copper to and in the home. But it does. It makes sense that a good regenerator close to the consumer could eliminate the need for anything fancier than a 12AWE cord. Similarily, a fully balanced system eliminates the need for expensive interconnects.

Mate you should be a pastor in the church of Flying Spaghetti monster

$40,000 for just one power cord, I would spend for nice speakers.

If I had a system like this, I wouldn't be able to sleep at night knowing that the electricity coming from the power plant is unpure, coming through regular power cables, not Nordost, that the only thing I could do anything about was the last few feet.

what you did is very clever, congratulations!!!!!!!!!!

"You need to let the cable settle in".... I don't mean to offend but... promoting pseudoscience isn't cool. This is why sound engineers dont hang around audiohile circles too much...

It is sad that people can't just enjoy the ride. I totally agree with you Jay, cables need to settle. It cannot be emphasized enough how important this is. Very much looking forward to the new "power" product you will be repping.

Sorry, but there is no "settling" of a power cable. That is just as bad as claiming audio performance improves with power cables.

you are correct to do what you do jay , i say check everything you can and decide for yourself if its worth the difference in money .......

angel dust, testosterone levels, etc have a huge impact on power cord performance.

Good video. Can't wait to see that A/B comparison. I would be SURPRISED if I hear an actual difference. Please just make sure it's blind to the audience. And I'd suggest that you if you have a poll where people can vote, you include amongst the voting options, "hear no difference" (in addition to "cord A sounds better" and "cord B sounds better", or however you choose to word it).

There's break-in, and then there's letting a cable settle in, if it's just been installed, even if it was already broken in. When it comes to break-in, I think most cable's and equipment take a full 1000 hrs of continuous use to be fully broken in.

Big believer in power cords. AND cables that match the system. Think that’s why I loved the Nordost Odin 1 power cords with the McIntosh gear I had. The more forward presentation of Odin matched well with the warmer McIntosh. Good video!

Jay much appreciate you sharing your gear and educating us .Thank you my man your gonna save me some scarce $$

The bigger question is, would you be better off taking that $40,000 and put it into better equipment versus power cables. In your case, you're already have top of the line ultra components, so that question may not apply to you. But what about those with more modest systems? Would anyone putting a system together be better off using stock power cords, and putting that money into a better amp, or preamp, or even speakers?
