So you probably have 50' worth of 12/2 Romex Solid Copper wire traveling from your main panel to the outlet for your equipment. Then you install 6' Sigma Power Cord for $2500 and you have better sound? Somebody needs to do a Double Blind Study

Question: Why cant the equipment internal power supplies not be improved to the point where full performance is realised as long as the supply voltage is in tolerance and of reasonable quality taking into account typical fluctuations and noise? For instance designing with larger regulation headroom, more storage capacitance? Is there a property in the cable that does not exist in an electronic component or practical circuit that cannot be fitted inside the equipment?

Considering the audio circuits are *after* rectification and *FILTER* capacitor circuits, (as close to pure DC as possible), how could the AC power cable influence the audio unless it is too thin of a gauge, and there is a voltage drop to the audio equipment power supply?

You said it right. , while conducting, the curcuit is passing all components and the color they each give off gets imprinted in the audio signal to a minute degree. So if a thin wire can strangle the flow a thicker wire will do this less. They each have characteristics beyond resistance only. Capacitance, fieldlines behave differently etc. Try lifting your wires off the ground... let someone else do it. blind test. Your equipment must have the quality to show it of course.

What I find interesting about subjectivists is that the quality they assign to things that are not scientifically measurable always match intuition. For example, silver, with its shiny surface sounds sharp while copper, with its reddish color, sounds warm. For power cables, the strong and heavy Romex sounds more bassy than the thin and flexible zip cord. That looks a lot like a psychological effect. But if people think it sounds better, even if it only sounds better in their own minds, why try stopping them.

In theory the only signal that should be in a power cable is 50 or 60hz, if it affects the sound then it stands to reason that the sound signal somehow resonates with the power cable, in that case it should extend from the AC/DC transformer as far as possible, preferably all the way to the wall. It would be interesting to conduct an experiement to see if the sound signal can be detected in the power cable itself, and possibly in other plugs on the same circuit.

The AMD (anger management device) is present on the right side of the video frame for when all goes wrong after assembly and testing at PS audio.

Do you use cryo treated cables?

What other frequencies would be passing through a power cable other than the standard 60 HZ line frequenciy in the US and 50 in other ares of the world? Would the primary voltage of an AC supply be modulated by strong current draw of the musical content's draw on the secondary of the supply? I know from transmission line theory that the type of conductor will affect the signal, but wouldn't proper power supply design minimize the effect of rapidly changing current draws furnished by the secondary of a power supply operating at these relatively low frequencies? Also is it possible to measure voltage changes on the primary side of a transformer while playing different frequencies on the amplifier?

I was lucky. I was @ a local hifi purveyor around 30 years ago when I got in on a demo by John Dunlavy. It was "testing " the sound of speaker cables. What John did was behind a screen that hid the playback components (but of course not his speakers which sounded excellent). He had an assistant hold up various cables. The same test track was played.Then the audience of around a dozen would comment on the sonic differences. I said I couldn't hear any which was my innocent & honest assessment which was regarded with loathing & smug contempt by the "audiophiles". When no one was looking John winked @ me. I thought to myself what is he up to? Turns out to the horror & disgust of the "audiophiles" who had waxed lyrical over certain high end looking cables when John revealed he never changed or swapped out a single cable. I think John made a strong point that day about the power of suggestion & some enemies with their pride wounded. Even though I never saw the man again he made one lifelong friend that day.

If a high end power cable sounds any different than a well made IEC power cable in the $10 range, then the power supply on the device being connected is poorly designed. Any power supply in a device should make the assumption that the incoming AC power may be noisy, and it should be capable of filtering that noise out. If it cannot, a snake oil power cable isn't going to solve the problem.

The only other concern would be if the geometry of the cord conductors is off, then one of the conductors could induce a small voltage into the grounding conductor. That could cause some noise problems (hum, buzz) in unbalanced systems.. But, that really should not be an issue. The talk here is nonsense..

I fixed it by re securing all the wires in the breaker box. I only lived there two years.

In this context, I'm sure he meant to say copper. But, aluminum, while less popular, is still used for electrical power wiring. Because it expands and contracts at a different rate than copper, there are lots of specifications on making connections and tightening screws.

Aluminum wire was often used in residential between 1969 and 1976 when the price of copper went to the moon. The aluminum wire would be 12/2 to handle 15 amps, whereas copper would be 14/2 for the same current capacity. Aluminum wires themselves are safe, the connections are the main concern for overheating and fire risk. Aluminum over time oxidizes, and the coating of aluminum oxide on the outer surface of the conductor is an insulator, and causes connections to heat, arc and expand / contract compounding the problem until the connection burns up. You can live safely in a home with aluminum wires, but the connections need to be checked for tightness, coated with anti-oxidant gel, and overall be done with care. Aluminum wire has zero tolerance for sloppy termination.

That’s an interesting question, normally connection of screen on ground on both ends is used by some for interconnects, replacing the ground wire, or in addition to a ground wire. First of all, I never tried that on PCs but it should sound different, as main cable properties change: higher capacity, lower resistance on ground, but, I’d assume less or different shielding effect, since current flowing up or down the screen as a result of emu/emr would alter also the el. potential of the housing connected via ground. The latter would not happen if the screen was not connected to ground on device side. Note it can happen that (stacked) devices, or to be more precise, their cases’ el potentials are oscillating against each other with the PC cords acting as inductances, and described screening variants change their LCR. I should add I once did it’s of PC cord variants on a CD player (Arcam CD92, which reacted strongly an PC cord config) and the ground configuration esp it’s cross section had a marked influence (with a clear sweet spot) on SQ, N&L kept unchanged.

Sort of in response Andy Delle's comment, when i first heard that power cable make a difference i said the same thing, "that seems like the dumbest thing i've ever heard of." But then i recall from technical school that i had an instructor tell me in no uncertain terms that me wanting to put a bigger capacitor in the audio path of my radio project we built that semester was not going to work. No Way! No How!!! Thank God i didn't listen. Later when i wanted help to get an audio op amp from Radio Shack to work, the power supply was oscillating so bad that it did seem hopeless, he said you'll never get that to work either. I not only got both items to work, i'm still using the audio amp 28 years later. The radio I destroyed by continuing to make it better. if I had listened to my instructor, he was actually my favorite teacher at that school, I would have missed out on hearing the best music played back on systems that play music the way I want to hear it. I've played guitar for 50 years and grew up pounding on a upright piano for 14 years. Almost all of the stereo systems that I've listened to do not sound like real music. They can sound really good but not like live music. My experiments have gotten me close. Power cables make a huge difference even on cheap stuff, which is what i mostly have (raising two daughters takes most of married income so audio is usually a low priority). I've replaced all the power cables with 12 gauge romax, it's cheap and it works. The only thing it doesn't seem to help that much is televisions. Tried it didn't notice any difference. But for audio it makes a huge difference. i was converted ten years ago. (I could give a ton of examples of how it improves the audio, but this is already too long. i'm an audiophile not because i have great hearing, just the opposite i have one eardrum covered with scar tissue from endless earaches when i was young. I need my systems to speak clearly to help me enjoy them). My favorite quote from Mark Twain is; "If you grab a cat by the tail you'll learn things that you can't learn any other way".

It's especially strange considering he's selling them and has a vested interest in demonstrating to his customers that his cables make a difference.

Have you ever tried running the romex straight out of the wall cavity (no wall socket or junction box) and terminated it straight into the power transformer in an amplifier (no back panel IEC socket either) to see how that sounds? Yes there are all sorts of regulatory/code issues, however as a one off test, it would be interesting. as in how far back from the amplifiers back panel does this flash cable have to run? To me, an ideal power lead should have a good twist in the three conductors & a good shield so that no AC mains born noise can couple into my intereconnects & speaker leads. Where I used to work, they used flat wide plated copper strap as earthing/shielding connection, as that gave the best results when they sent their gear of for EMI etc testing/certification, so then would having a dedicated wide flat earthing strap from the back of your audio gear to a dedicated earth point help in getting the noise floor down etc.

Regardless of whether there's a noticable difference: - if the cabling in your home is 12gauge solid-core aluminium.. then having your powercord be 12gauge solid-core aluminium has ZERO effect on the ability to supply your electrical device with power (aside from the fact that the total length of cable is slightly longer). If having a hollow core stranded cable has an effect on the sound produced by your electrical device that simply means that your device is influenced by power-delivery.. which means your device has poor power filtering/cleaning. I would much rather buy a device that properly cleans the power it receives than a device that passes the flaws in the power delivery along to the output of it's (amplified) audio signal.

I would suggest that since there is not a scientific theory to explain any audible differences when such cables are used, a double-blind test would be in order. It would be quite easy to do with employees and visitors. This kind of test would rule out confirmation bias as the source of perceived improvement in sound -- and any statistically significant difference shown in the test results would be a good substitute for the scientific explanation or theory that is lacking.

today i made up a new Furutech DPS-4.1 Limited Edition High End Audio Grade Power Cable.i fitted the cable with a high end furutech socket and plug. the cable cost £ 400 per meter.i made up a 1 meter cable. when i fitted the power cord into my ps audio bkh 250 amp it defiantly changed the sound.i run monitor audio pl 300's which are on the bright side in the highs.the cable knocked off the harshness from the highs and they now sounds much better. i have DIY'd lots of power cords for myself but usually they are no way the price of this cable .i usually use lorad 2.5 silver plated cable to which ive had no issues.however after listening to this new cable it looks like im going to have to upgrade them all again. the copper in the new cable was more harder and it cut more brittle than normal copper.that must be the single grain crystal design making the difference. plus this new cable had many layers of different materials to keep the noise out.i know it sounds unbelievable and im all for been very weary when it comes to this snake oil subject and in the beginning i didnt believe any of this including speaker cable and interconnects.but after a few years of asking the same old questions , i am starting to believe cables do make a difference.

I watch your video all the time find them very good and informative. Have a few questions on power cord burn-in. Recently i purchased a PC, it took 300 hours of burn-in time. Why don't the manufacturer or dealer offer this service, even for a small fee i can accept? Does burn-in machine that does it by some stereo shops damage the PC or cable in general?

@hugoromeyn4582

No, it won't damage the cable. There's a huge difference in the way you burn-in an interconnect and a power cord. Interconnects are burned-in by putting them on a slightly higher Voltage than they're normally used in a system (to speed up the process), while feeding wide band noise trough the cables. That same process can't be done with power cords on such a machine. Because of the low Voltage and current, it makes no sense. It will even take longer to burn them in because they are much thicker (more mass) than interconnects. The only way to burn them in, is to let current flow trough the cable.

Have you tried a double blind test?

Yes Please. I'll like some more.

It is interesting about the solid core vs. stranded. I have done this experiment myself with both power cords and speaker cables and the solid core wins out every time. I find that using several thinner solid cores, each individually insulated, seems to be the sweet spot.

Julia Set That doesn't necessarily mean anything. It's dependent on the voltage generated (volume), speaker impedance and length of the cable. Anyway if you can perceive (or better measure) a difference, that only means you are choking the current flow, which basically comes down to using your cable as a tone control. Not it's intended purpose. But eh, whatever makes you happy...

Paul, in your post you stated romax with aluminum conductors, I hope you ment copper. Also I can't understand how the lab power cable with the solid core conductor and stranded conductor would make a difference when my whole house is wired with solid core. I can see it may make a difference in speaker cables.

I have heard these things from a friend of mine, who bought an expensive power cable for himself. He say it's better. I don't hear it, despite i do have good hearing, really. So i'm a bit sceptical about this. The power travels into your wall socket from the street, and you don't know what kind of cables are in your wall, especially if you living in an older building. They can be some crap quality cables from 50 years ago, or more. What's the point of using a crazy expensive 1 meter long cable, if those Ampers travelling 40-50 m in a shit quality cord? You want to tell me, that 1 m long "super cable" is going to do the miracle? I don't thik so...

Hi Paul. Thank you again for the video. Very good one. Some weeks ago I've changed the power cables of my system (stock ones for DH Labs AC Power Cord), along with the amp fuse (stock one for Hifi Tuning Supreme). I also put a power AC filter (Bada LB5600) and a couple of PS Audio Noise Harvesters. I didnt try the upgrades separately (I know a mistake), but the sound today is SO MUCH better: fuller, stronger bass, wider and deeper sounstage, much more detail, better dinamics, etc. I can't tell the impact of each upgrade, but after seeing your video, I guess the fuller sound and stronger bass should be a result of a better power cord because I've read that filters and fuses improve mostly highs, detail, background and soundstage. What do you think? Am I right?

I was a skeptical as they come when I first heard about these ubeaut aftermarket power cables. I had bought some fairly expensive interconnects and speaker wire, and could not say I could hear any real difference to speak of from any of them. So why should a power cable which has nothing to do with sound make any difference? Well I got a Consonance power cable thrown in with a Butler Audio amp I bought, and I was astounded by the difference. I kept switching back and forth between it and the standard cable to make sure it wasn't my imagination. No cable to that time had ever made such a big impact on my system as that cable did. I have since bought some Furutech Alpha series power cable and have made up my own cables. The weird thing is not every device shows the same massive gain. Some are so small it is barely if at all noticeable, while other devices are like a punch in the face.

Maybe not an oscilloscope, but an audio analyzer would. Paul claims that bass is lost on stranded and the highs are thin with solid core. Clearly the cable is affecting frequency response or maybe distortion at certain frequencies. I find it odd as an engineer for another engineer to discover a combination of materials which apparently makes a difference to sound, yet is totally unaware what change is happening and has no curiosity to investigate. It's especially strange considering he's selling them and has a vested interest in demonstrating to his customers that his cables do make a difference.

@@sswpp8908 All you need to do to tell whether there is a difference is to LISTEN. The problem with measurement tools is they only measure what they are designed to, and our auditory systems pick up on things that aren't shown on an oscilloscope.

You should build vibration damping into every unit as that definitely improves the sound.

1:10 Cambridge! The center of the Great British sound! I have a CA Dacmagic Plus. I can highly recommend that for digital audio playback. You have a valid point on the oversized transformers, when it comes to impedance. It is called high damping factor. But "high end" power cables is just beyond my suspense of disbelief.

I still say snake oil! Yes, if the power cable you are using is very small gauge and/or aluminum wire, a heavier gauge cable will make a difference. BUT if your power cable is already a fairly heavy gauge, copper, good connectors that really grab the pins in the receptical they are connected to, NO it is ridiculous! Just think..... what is the wiring INSIDE the amp like? How about the gauge used for the power switch? The gauge used to wind the power transformer? The weakest link WOULD be a cheap power cable, but if it is good quality and heavy gauge, at least the same gauge or heavier than the wiring used INSIDE the device you are powering, a high priced power cable WILL NOT MAKE ANY DIFFERENCE!!!! What is the wiring from your breaker panel to the receptical? Romex? Stranded? How about the power drop from the pole to your house? Aluminum? Copper? How about the distribution transformer on the pole? Usually they are wound with flat copper strips. How good are the connections from the transformer, to the power lines to the drop to your weatherhead to your breaker panel bus bars to the cips on your breakers to the wiring conneting the run to your receptical? How good is the receptical? Is is spec grade or cheap $0.39 bargain basement receptical that barley grab the plug pins? There are TONS of things that are between you and the distribution transformer and a measly high dollar 6 foot power cord ain't gonna make much difference!!!!!!!!!! There is no real mention of what is being compared to... is it a cheap light cable that you are using to power your computer monitor? I STILL say SNAKE OIL!!!!

Howdy. I wonder if Eddy currents in the wire plays some role. There will be Eddy currents in a wire. That is my understanding. Stranded wires will have surface resistance between strands. Eddy currents will generate losses. The equivalet for solid wires will be the specific resistivity of copper or aluminium. Smaller losses. Have you tried building up the wire using enamelled copper strands ? Kinda like Litz wire. I understand that would reduce Eddy currents. Regards.

@ Rolf Hawkins That's probably because you're looking at this the wrong way. When I purchased my Rotel amp 18 years ago, there were none available for delivery, so the dealer lent me a Sansui amp of nominally the same capability. When it was replaced by the Rotel several weeks later, there were clearly audible differences, mainly in the bottom octaves. The only obvious difference between the amplifiers was the weight of the much larger transformer and power supply capacitors in the Rotel. When I needed to replace the Rotel temporarily with a Sony while I serviced the Rotel a year or so ago, the phenomenon of changed bass response was also readily perceptible. Even the missus noticed! The Sony, like the Sansui had a much smaller transformer. Perhaps it's a case of some engineers preferring undersized parts to save on weight and/or cost.

Of course a power amp is a totally different topic than a phono amp, preamp or DAC when it comes to having headroom in the transformer. Indeed, for a power amp, you are facing some dynamic load condition that depend on how loud you play and how hard your speakers are to drive. It's good for a power amp to have a transformer that can give you extra power that you need especially in the bass when playing loud. But Paul is talking phono amp...LOL

I think it's the matching of different cables to different speakers and rooms that make the difference. For example I could be using expensive wires that sound fuller and with more bass, but if my room is small and my speakers big and too energizing that would be detrimental and so I'd be better off with a less expensive cable and a thinner sound.

I have a couple questions Paul. 1 are you using aluminum for your electrical wiring in your buildings? That's a no no. 2 do you know about "geoengineering" weather management programs? When you go to England try greenlaning , dirtbike preferred or walking but you will see more country side that way.

I was a skeptic of power cables, how on earth the last meter of connection from the grid to my amp could make a difference, until an installer brought along a fairly "beginner/cheap" hifi power cable, I immediately noticed the difference in both sound and visual, it sounded louder and contains more detail at the same level, and the color of my projector has given a more darker or a few shades of color, like scenes somehow has more details as compared to before. at first I thought it's psychological and I was fooling myself so I had the guy conducted a blind test to me, watched the same scene of Fast 5 over and over again, and I could pin point with 100% accuracy of guessing which cable he is putting in each and every time, the same explosion scene looked and sounded different! I was blown away, til this day I still don't understand how it works but the installer did sell me this cable, he knew from the start I was going to buy it as soon as he puts it into my system, what a sale. I tried telling my friend this story but without inviting them over they would just treat me like a lunatic !

Even 1% less electrical transmission loss in an electric car internal wiring would be worth millions alone. Why is consumer audio the only application of such technology?

Paul talks about firmer bass through the solid cable and better highs through the stranded cable? Wouldn't these differences be measurable with something? a change in shape of the bass wave or a dB increment... an oscilloscope?, so far in my life as an enthusiast, if the is a difference in the sound, it can always be measured with something.....other than just golden ears. I understand the theory of the two cable constructions on speaker cables........but how does this transfer to the power cable which is only coming in at mains frequency.......there is no high frequency component by which will travel better down the stranded cable. As others have pointed out, and what about the other 200 miles of wire that may be between your amp and the power station- shouldn't it get the same treatment. no, I haven't tried to see what a difference it would make, but even if there was a difference, its unlikely that the cables could be swapped out quickly enough for my acoustic memory to register, but if it could be set up somewhere I'm willing to give it a go.

Great thankyou Paul, but surely that means we need to change the cables from our supply transformers out in the field to our power outlets aswell by using both solid drawn and flexible conductors. Mine are approx 400m across the field so this could be quite expensive. I'm in no way dissing what you have said but find it hard to believe that a 300mm cable change could alter the sound that much when my supply cables are 400m to the transfomer and then 64373m from the power station. Thats an impressive 215,910 times longer than the my amp supply cable. Sorry.

The only conclusion I can make of all this high-end power lead thing, is that there are quite a few issues with having a power lead anywhere near the back of your audio gear, as in speaker leads & interconnects. otherwise, as you said, we are only talking 0.0001% or the wire between your gear and the power generators. Maybe high end needs to run on batteries, and keep the AC well away. - as in high end leads couple less into the surrounding rats nest behind your HiFi.

What about a grounded conduit, #10 or #8 even #6 copper conductors with dedicated grounds that lead into an 8ft ground rod 🤔

Excellent explanation. No one can take exception, but of course they do. I make my own power cords. Only about 1.5' and shocked to find they make a substantial difference. I have 400 amp service to my home, so 3/4" thick copper cable from the transformer to the house. But here is the rub. Only one 14 gauge copper wire to the system. 30 feet of 14 gauge and somehow the last 1.5 feet makes a difference. Who cares. I just enjoy the improved sound.

1. So when every outlet in my house is installed with stranded wires (as is the standard now) in the wall, I can't get the best sound possible? Bummer. 2. If solid wire is so great, then why does the unit you show have thin stranded wires leading from the main connector to the big transformer? 3. BTW: Power cables are stranded for a good reason, it's so that they don't break when you bend and twist them as a normal cable would be.

I hate to complain about free videos, but people’s time isn’t free. 10 minutes into a 13 minute video, and still hasn’t started to answer the question. It’s finally answered in the last minute or two, but it’s a very brief and simple answer because there’s no time left to go into detail.

Inductance and capacitance of the cable are important to some extent, due to interactions with the transformer affecting how it responds to demand for load, but remember that a coiled up cable will have much higher inductance than a straight wire, and that's probably a big part of why you've found better performance from solid-cored cable, (coiled cable will also generate a lot more EMI). Before anyone starts spending money on power cables, everyone should start out with a pack of cable ties. Sort out your cable management, get all the power cables into neat straight runs, making sure that AC is as far from DC and signal cables as possible. If you're confident cut the power cables down to just the length you need so that there's no excess to coil up.

As long as the power cable meets proper certifications and is being used for its intended purpose, it will not make a difference. A linear power supply is built with provisions to manage minor fluctuations from the input AC -- which are far more detrimental than any inductance and capacitance related issues. I think Paul here needs to read a little on how linear power supplies actually work and then do some proper blind testing with these cables of his. This video is pure horse-puckey as Paul so eloquently puts it.
