Do powercords make a difference in sound?

Hi Byron, agreed that this can and should go no farther. However, just for the record (and perhaps a better understanding if I failed to make myself clear, which is probable), I never said that a power cord's sound changes with listening position. (As it clearly does with a speaker -- although of course a speaker can only make a sound at all when fed a signal that by necessity involves power cords, and more to my point, a power cord can only be heard through the lens of a speaker in a room at a listening position.) What I did say was that a listener's impression of a power cord's sound can change with their position. The word "impression" to me invokes subjective reaction, evaluation and judgement, both qualitatively and at the basic pro or con level.

I think much of this discussion focuses on power cord differences that are of low magnitudes. I have certainly experienced instances where I had to struggle to decide which I preferred. Finally, I decided to keep which ever pc I owned.

But I have also had experiences where hearing which pc was better is quite clear.

I think that if the power supply in your component is designed properly and the stock power cord has sufficient gauge to deliver the current demanded by the component there is no advantage to upgrading.

cables are like tone controls or flavors of icecream. there are so many from which to select.

sometimes you might prefer one flavor, other times, you might prefer another.

Liguy, have you ever heard a properly designed power supply?

Mrtennis, is it possible to design a perfectly neutral cable? If so, what theories would lead you to it?
