How can power cords make a difference?


I am trying to understand why power cords can make a difference.

It makes sense to me that interconnects and speaker cables make a difference. They are dealing with a complex signal that contains numerous frequencies at various phases and amplitudes. Any change in these parameters should affect the sound.

A power cord is ideally dealing with only a single frequency. If the explanation is RF rejection, then an AC regeneration device like PS Audio’s should make these cords unnecessary. I suppose it could be the capacitance of these cables offering some power factor correction since the transformer is an inductive load.

The purpose of my post is not to start a war between the “I hear what I hear so it must be so” camp and the “you’re crazy and wasting your money,” advocates. I am looking for reasons. I am hoping that someone can offer some valid scientific explanations or point me toward sources of this information. Thanks.

Just want to say thanks for all the negative votes for my last post, since it matched my expectation that only the voiceless weasels would respond. 702, you are right this expectation thing works!
Albert, I was hoping you were going to set up the blindfold kissing thing. You must know some women that could take part. The cloths pin and gloves seems a bit kinky though. I'd rather take my chances with all my senses thanks.

As much as I want to hear your system I will pass on the big group, I already know the outcome so if you don't mind, I'll hold off until I'm in Dallas and hopefully hook up with you for a solo performance. Thanks for the offer, I hope Steve, 702, Jostler and now I guess Fpeel will join you. (if they don't, well it only shows there intent again!)I would love to see there faces!

Anyway keep working on that blind woman thing and thank-you for the gracious offer. J.D.

P.S. I expect the free dinner offer is a standing offer?
Oh no: Were you being sarcastic as well? The lines are becoming very gray to me at this point.
