Geoff when will you ever stop peddling this nonsense and waste our time?
This is a forum for discussing things related to audio and music, so I think Geoff's comments belong here - whether you approve of them or not.

When you say Geoff is wasting "our time," please tell us on whose behalf you are speaking, other than yourself.
So I disconnected all of my power cords and replaced them with the stock cords. I didn’t tell my wife what I did, but asked her to listen to a couple of her favorite songs. Her reaction, what happened to the bass, his voice sounds dead, it doesn’t sound good, what did you do? Hearing improvements makes one a believer. Honestly, it’s so simple...if you don’t believe power cords make a difference through listening, don’t buy them and be happy!. If you hear a difference than buy them and be happy!

@cleeds ,
The statement he was contesting was that directionality makes a difference on a power cord. It was in this case the voice of reason; if you think about it, if a cord is working with AC power, directionality would cause the cable to heat up and fail or cause a fire. Clearly this isn't happening and on a large scale- the idea of directionality is nonsense, and is a topic that should not be discussed beyond debunking it.

Its unfortunate that Geoff continues with this as essentially his comments are trolling.

Now if you engage in the idea of a directional power cord, then you are wasting your time, unless the entertainment value of doing so is valuable to you. Certainly it won't make any difference in how your stereo sounds!

>>>>>>>Of the many peculiar things I’ve seen you say this one takes the cake. 🎂 Happy birthday! Where do you come up with this stuff? “Directionality would cause the cable to heat up and fail or cause a fire?!!” OMG!! 🔥Now I’ve heard everything. The tiny strands of wires in all power cords are directional since all wires are directional. But there I virtually no difference in how electricity is conducted either direction. Are you pretending to be slow?

Since power cords ARE inherently directional. We can assume your statement must be FALSE since there’s a 50% chance a given power cord is actually in the correct direction from the standpoint of directionlity. However, most manufacturers have been a little bit slow to catch up to Audioquest in this regard. And they’ve been slow to catch up to Audioquest in controlling directionality of HDMI cables. Do you seriously believe Audioquest advertises they control directionality for their new power cords to ensnare gullible and naive young well-heeled audiophiles in their clever directionality spider web? Give me a break!

For amp manufacturers, obviously the wire directionality is even more of an issue, given all the wire in the amp, including transformers, etc. are...you guessed it...directional and should therefore be controlled for directionality from the get go.

I have on many occasions. And for things like this:

“Directionality would cause the cable to heat up and fail or cause a fire?!!” OMG!! 🔥Now I’ve heard everything.

The above quote contains several contradictions plus a personal attack; it is based on the falsehood of 'all wires are directional'. Its easy to parse out: if a wire were indeed directional, it would have a higher resistance or impedance with current going in one direction than if current were going the other direction. This increased impedance would over time heat up the resistance of the wire in the same way that all resistors do when current flows through them.

In an AC power cord, current flows each way 60 times per second. So a wire that somehow favors one direction over the other (were that even possible) would be unsuitable for this application (it would heat up...not a good power cord behavior); that is why there are none. If a wire conducts better in one way then the other, this implies a diode and diodes cause rectification (conversion from AC to DC, which is a non-linear function) which would make the power unsuitable for the power transformers used inside the audio equipment. Further, diodes in series with any AC signal (for example an audio signal) are a source of distortion; in fact they are used in effect pedals used by guitarists to make distortion (and are known as 'fuzz boxes' or 'fuzz pedals').



It’s a sure sign you’ve lost the debate as soon as the T word makes its appearance. Oh, well, better luck next time, dudes.

Atmasphere, relax. Nothing is going to heat up or explode. I realize you almost for sure have not (rpt not) been following the whole wire directionality saga or you would not be driving so hard to the basket. The difference between resistance measurements for fuses was found to be quite small, although there were in fact differences. But certainly nothing to worry about. Less than 5% as I recall. Maybe less than 2%. Since wire IS in fact directional don’t you find it a little strange nobody’s House has burned to the ground? 🔥 Hel-loo! Differences in resistance are shown in the data sheets on the HiFi Tuning web site. These data sheets have only been mentioned and linked to like a Bazillion Times in the past several years. And it would certainly be easy enough to measure any wire yourself, you know, assuming you were the least bit curious.

Have a nice day





I know nothing is going to heat up, because wire isn't directional. The links you've provided in the past go to fake 'data' that can be safely ignored. We've already covered on different threads how its impossible for a fuse to be directional, and on those threads I provided the reason why some people hear a difference when the fuse is reversed, and how to predict it, using a simple DVM.

@cleeds I believe have have made my point. Geoff will continue to troll, but the facts can't be changed by that.
Don’t you even realize you cannot win an argument by calling someone a troll? This is SO funny!  You don’t even know what directional means. You have exactly zero evidence to support your case, in any case. Case closed. That’s 3 cases in a row.  Have a wonderful day.
Having Ralph call someone a troll is like Mother Theresa uttering an F bomb.
At least in my honest opinion...
And, Elizabeth is more than that. She's a lady. (not in a chauvinistic way ;))

Hi guys
I was not a believer until I tried a cheap and "as short as possible" DIY cable.
It made a notorious difference most of all in the DAC, I guess it should be that way because it works with the small signals.
It was really easy to make. The only "special" ingredient was a cable that I bought to my regular electric supplier, one it has 3 cables (positive, neutral and ground) protected by a electromagnetic isolation composed by an aluminum paper cover plus a metallic wired tube shaped cover plus the classic rubber black external protector.
The IEC plug and the plug for the wall were standard ones, being the IEC plug not the best quality at all!!
Well, that simple cable cost me about 5 dollars and 30 minutes to make it, Im not handy on electrician tasks. :-)  
It really made a difference.
I could not believe it, but it was true.
If I did it, anyone can do it and try it, at almost no cost.
So theres no excuse for the skeptics not to try it and keep on talking.
All you need is a nice system, good source, ears used to listen hifi systems and some time. 
It will be the cheapest upgrade ever!!

@atmosphere-thinking more about the diode effect analogous to a fuzz pedal, what if the effect was much more subtle than a fuzz pedal yet still perceptible to the human auditory system?  Possible? Could it be measured, and if not with current technology, still be audible?  This is the part that I find truly fascinating: that we may be able to hear very subtle differences that we have yet to measure accurately enough or even account for.

Your beef is really with the moderators, Ralph. Geoff seems to be playing by the rules here.

It is a a fact that you will hear an improvement with a cable in a better sound system. By the way, not only the cable are important but also speaker binding post, a bad one would shrink and distorted the sound and a good one would make the music bloom.  I just do the change and wow !

"

Of course yes that is a completely factual statement as many here on the Audiogon forums can readily attest based on first hand experience with they're Music Reproduction Systems but equally true is that there are "naysayers" hear who believe as a matter of faith that such an audible difference is impossible so even though they have no proofs of they're own they often demand proofs from others it is most unusual! As if that is not alone enough to "boggle" the mind these same "naysayers" will claim to have science on they're side and that you are engaged in a fraud or snake oil.

The mind of the Uber skeptic is not really that hard to figure out. As it turns out they really don’t care that much one way or the other. They don’t really have a dog in the fight. 🐶 It’s all about the action. Like whack-a-mole. Action...reaction! It’s sooo obvious. Even hear the expression, “Don’t feed the Uber Skeptics?”

@jc4659 If the effect were there to begin with, I suspect it would be audible. But its not. The reason you hear differences between power cables is not directionality. Its voltage drop, plain and simple. Some at audio frequencies, and some at ultrasonic frequencies, depending on the rectifiers in the power supplies of the equipment used, as I explained earlier at the bottom of page 4 of this thread.

If there even was directional wire, power cable manufacturers would be working really hard to build cables from non-directional wire since it would sound better.

Your beef is really with the moderators, Ralph. Geoff seems to be playing by the rules here.
@cleeds  The first statement is true, the second is not. Geoff's MO is not to only to try to refute arguments (I've no beef with that) but also to make personal insults and attacks on anyone that challenges his mythology. This is one of the definitions of a troll. To be within typical forum rules, the principle is "attack the argument not the poster". For now, moderation seems to be content to tolerate trolls, which is unfortunate, as it makes it harder to wade through threads to find the useful bits.

As I opined previously, I’m not so sure Atmasphere completely comprehends what “directionality” refers to. Judging by his own words I’d say he doesn’t. No offense.  Audioquest controls directionality for not only their cables and interconnects but also their power cords. It’s not rocket science. 🚀 By controlling directionality the customer is assured of the best sound. All that is required is for the manufacturer to be AWARE of the issue and to control the manufacturing process accordingly. In fact the customer doesn’t even have to be aware there is such a thing as directionality. This is not some new tangled fad. Wire directionality has been known (by those who know 😀) for going on 20 years, which if I recall was the period of time Rip Van Winkle was asleep. 😴

Whoa! Look at me. I just finished saying don’t feed the Uber Skeptics. My bad.

have a wonderful day!

to Willemj,
correct me if i'm wrong but have been you going on about after market power cords without having tried ANY in your system ("Do you think I am that mad?")? Are you saying you have no experience with after market cords?  I'm going with that that's not possible because anybody that expresses so vehement an opinion without actually having listened to a power cord or two is simply a boob. You go on about the science but why not try a little science experiment of your own and listen to a few cords and THEN express an opinion. At  least it will be informed. You might even learn something. From my vast experience listening to a great number of power cords, there is NO doubt they have anywhere from no affect to a minor to a profound affect on the sound quality. Do you think that everyone who purchases after market power cords is naive or stupid or deaf but you, who have never listened to an after market cord know that they don't affect the sound? Stop wasting everyone's time with an uninformed opinion. Or I could give you an opinion and waste your time  about a book i never read.
   Regards, Charles

Can someone who has had positive experience with aftermarket power cords cite specific examples of what they heard? Which album? Which passage? What specifically? Was it really "better" or, just different? If it was"better", what do you think was causing that deficiency in your system in the first place?
Better is always going to be in the ears of the beholder. 
Good systems aren't deficient they will produce music differently with a variety of different power cords but I don't think it can be proven to non-believers satisfaction because it's a matter of personal taste and hearing ability.
Agreed but trying to get more insight into what people perceived to be as better. For example is there more Bass, is there less sibilance in the vocals, are some of the highs less screechy,.

@pawlowski6132 I understand your desire to gain info about cable characteristics from others. It’s kinda circular, as that information relies on gaging and aligning the contributors’ subjective listening (and hearing) impressions with your own. And I hazard to suggest this quest is further complicated (and frustrated?) by objective differences in audio systems and room acoustics.
So these people that claim power cords make no difference because of scientific therories. Well science only knows a small part of what there is to know. They can't explain ball lightening!!!!! That's Just in the electricity realm. If it can't be explained it doesn't mean it doesn't exist. Romex is solid core house wiring. Doesn't it  make sense to have a solid core power cord(after market multi strand) to finish the connection? I've heard the same positive effects of after market power cords that others have heard. How about metal whiskering? Scientist don't understand the mechanics of it and it has caused equipment failures. When metal is stressed, projections have been observed. Could that be the reason why sometimes when you bend or stress a cable it sounds different!! Cryonics is another where scientists don't know the full reason why electron emission increases in the absence of light. I got these off Wikipedia unsolved problems in physics. There is around 50 listed.

And then I thought, the exact same wire I was using is still in the extensions. So WHY is that not making the later wire the same as it is on it’s own???

Anyway, I do not have the answer.
However it IS a project anyone could do. make a PC out of the same sort of wire in the wall Romex, whatever. See how it sounds? Then remake the PC with your own audiophile wire. And see if/how it changes.
Romex is very high performance but is illegal and dangerous for use as a power cord. That is why all power cords are flexible wire. The other requirements for a good power cord were outlined on the first page of this thread.

@ pawlowski6132, you asked for specifics, here goes. I've installed a PS Audio BHK Stereo 250 amp recently and have been working to get the tonal balance of the system fine tuned to my liking. I had few power cords to try, none terribly expensive; Mojo Audio copper ribbon, Wireworld Eclipse, DIY Furutech FP-S032N, & DH Labs Red Wave. All made subtle changes but all were slightly off, either too much sibilance on closely miked recordings accompanied by a bit of tonal dryness or a lack of liveliness if they didn't accentuate upper registers too much.

This illustrates what I wanted - I was recently listening to a live performance of a small Baroque ensemble and when the period Oboe was played with gusto, it blatted, squawked, and sounded harsh but yet it didn't make you recoil like a harsh recording can. When the soprano let lose with a fortissimo passage, that was also harsh but it didn't make you recoil like you might when listening to recording playback. 

When I installed one of PS Audio's AC12 power cords on the amp, the amp hit its stride and was much better balanced (within the limitations of the recording.) Bass and treble were in balance without exaggeration, and there was far less tendency for previously excessively sibilant recordings  to sound too harsh. Harsh musical elements sound harsh but without as much glare as was evident previously. 

Admittedly, the differences in power cords are fairly subtle and I can understand how some would consider the costs to be out of proportion to the benefit. 
Has anyone been able to explain why power cable would make a difference?  Or this thread is basically a pissing contest.
There are many reasons why some power cords are better than others. It’s analogous to why some interconnects are better than others or why some fuses are better than others. It’s not rocket science. 🚀
OK. Purity of metal, gauge of conductor, geometry of conductor(s), dielectric material, length of power cord, stranded vs solid core, silver vs copper, broken in properly vs not, quality of connectors, cryogenically treated or not, controlled for directionality, e.g., the new line of power cords from Audioquest. Did I miss anything? 
Actually I did.  I agree that power cords make a difference because I had first hand experience.  I bought some beefy power cords and the sound becomes noticeably better - the soundstage becomes more stable, better separation, and the mass string which used to sound a bit harsh now quite a bit smoother.  I think you need some good system to tell the difference though.  I used to have some crappy system and it's was hard for me to distinguish the sound with different component but my system now is a lot better so it's easier to tell.

I was asking if anybody had a good well thought out explanation?  I have my own interpretation.

You can look at this both ways.  The power cord is the last 3 feet of wire going to the power supply, or it's the first 3 feet that the power supply sees.  Before, I would have said the former.  But now I tend to agree more with the latter.

what would be your interpretation of this explanation... Power Cables Technical Paper
There ARE solid core aftermarket power cords available commercially.
Yes- I'm sure there are. But they don't meet OSHA regulations.
Has anyone been able to explain why power cable would make a difference?
Yes. See the first page of this thread.
