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.

Nrchy, don't start that scientist crap again. I am sick and tired of reading the sos.
I don't know how many of you out there have read the Mike Van Evers explaination of why power cords make a difference but IMHO it makes no logical sense at all. Any other comments out there?
I had stock power cords on my amps.On certin tracks i would get bloated boomy bass.I changed the power cords to some homemade 14 gauge well insulated and shielded cable with high quality IEC and Wall plug.
Right offff the bat the bass came in and no more bloated and boomy bass.
I dont know the science but the sound is better.
Just read the white papers on the vansevers website. This guy could give the Brothers Grimm a real run for their money.

The powersnakes website makes the most sense, until it gets to the magic stardust part.
