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.

Has anyone else heard that the guy who continues to toot his own horn is the same guy that can not get anyone else to toot it for him?
Is any one else as sick of the tooting by the high and mighty as I am? It's all clear to me now!
702, ewe say:

"I've heard many, many audio systems of exceptional quality that had nary a designer PC, and couldn't possibly be improved by adding any..."

this blatant disregard for scientific method is pitiful. i can't believe we are still arguing w/someone who purports to believe in scientific method, yet completely ignores it, & who won't even trust using the most sensitive aural measuring device known - his own ears!?! 702, WHAT ARE EWE AFRAID OF??? are ewe afraid ewe mite be wrong? afraid of discovering science HASN'T yet discovered all the answers? afraid that yule have to spend more money on wire?

jadem6, 702's horn tooting is outta tune - whether it's live, on a boombox, or thru albert porter's stereo - w/or without designer cords... ;~)

Guys, haven't you figured it out yet? 702 is getting exactly what he wants. It's not insight, education or sharing as with most of the participants here. It's your collective goats.
Fpeel, we have three choices. First, engage with 702, arguably letting him get our goats, but possibly driving the debate to some conclusion (eg. Jostler). Second, ignore him completely, thereby causing new (and other)posters here to be intimidated from posting any of their opinions, in fear of unchallenged attacks from the likes of 702. Third, not reply to 702's posts but vote against him.

I agree that there are problems with the first alternative. But I am more concerned about the second alternative as I have seen this outcome eventuate elsewhere and this forum therefore degenerate into the closed-minded talking to the closed-minded, getting solace from being right. The third option may be preferred by some, but I see it as the weasle's way out. If I disagree or disapprove, then I do not intend to hide behind the voting system.

Therefore, regardless of 702's motives, I feel the necessity to react to his contradictory position. If he, as you suggest, continues to post asinine comments here purely to feed his immature need to get a reaction then I reckon he will get a reaction until he grows up or goes away. If this feeds his need for attention, he is one very sick puppy, and most certainly not one that should be left to intimidate posters here.
All good points, Redkiwi. Personally, talking to the collective brickwall grew old quickly and feeling it was a waste of energy choose simply not to do so. Circular arguments tend to have that effect on me. There are far too many other interesting threads available to feel any sense of loss. In any case, it certainly wasn't my intention to encourage anyone to alter their approach.

Anyway, whatever happened to "RHUBARB!"?
