How come a power cable changes the sound?

i'm asuming you were talking about the shunyata cobra and their blk mamba, when you said "bsolutely no diff i sound". hmmmmmm, 've listened to both of these cords extensively and must offer a different finding. while maintaining a family-sound, the two cords are quite different in their aural affect on, at least my system. the cobra sounds much like the king cobra, but sounds much better than the blk mamba. my findings on this matter are not unique, as i have spoken with a number of othre owners of this equipment. i agree that cords and cabling are very listener AND system dependant: thay all cord will not have the same affect in all systems. in spite of this, i still stand by my observations on the cobra and blk mamba, the differences are large. mike

Science may not have the answer for everything, but that's not a reason not to ask pertinent questions. The ear is a marvelous measurement system, but it is not infallible and on the head of an unskilled listener, it's not particularly reliable. By this I mean the results are not repeatable in a statistically meaningful way. I suspect a few readers will say "Who cares?", and they may be right. Still I wonder why I can't find a reasonable explanation of why power cords make the sonic differences that some attribute to them. BTW, in no way should my comment be construed to denigrate any persons ability to hear or the validity of what they report. I'm just interested in an explanation.

Check out the following link for an informed perspective. http://www.audioasylum.com/audio/cables/messages/13538.html Also, just becuase a power cord doesn't make a difference on one system, it could under a different set of circumstances. Please keep an open mind and give it a try. I've tried different power cords on my equipment and it made very little difference, but that doesn't invalidate the chance that certain equipment will respond better or that certain areas don't suffer from more/less RFI/EMI.

Many of us aren't satisfied with standard romex in the walls, nor are we with standard or lower grade cabling. Some of you remind me of the fable about the fox and the sour grapes. That said, I agree with avguygeorge wholeheartedly.

Does DTF stand for Deft? Maybe you are right about "vivid imaginations"...Maybe I am the leader of the audiophile cult..... we shall take over your mind with needless ways to spend your money...you are in our control...It is all part of a great conspiracy...Every cable manufacturer is part of this conspiracy....All audiophiles are bumbling automotons that hear whatever we tell them to hear....If you stay an "audiophile" your days will be numbered...If you do not come to your senses (like the majority of the smart people and buy a Bose wave radio) then we will brainwash you too.
