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.

stevemj, in yer second post to this thread, ewe say it all, & i'm sure everyone who feels power cords make a sonic difference wood agree w/ewe. you say:

"...If your Purist cord does improve the sound it is because of some phenomenon outside the known laws of science..."

NO KIDDING!!! so stop denying what others hear, yust cuz yer science is so INADEQUATE!!! is yer science's INADEQUACY why yure so afraid to listen yerself?

jordan, in yer recent post, ewe yump all over kitch29, saying:

"Your lack of knowledge of science, electronics, audio, the definition of a theory, EVERYTHING that you mention in your diatribe is so staggering as to be beyond comprehension. The number and magnitude of fundamental errors in your post is truly frightening"...."You'd be wise to take a beginning science or engineering course, and get at least a modicum of understanding (rather than just pretending to) before spewing forth as you just did. It's really quite embarrassing."

the only ting frightening or embarrassing is yer response to his post. basically, all he's saying is what stevemj said, only it took him a bit longer... ;~)

i suggest *ewe* wood be wise to go thru his post & refute each of his "fundemental errors" one-by-one, before condemning what he says in such an off-hand, non-descript, rhetorical & rude fashion.

stevemj, i'm sure all here will be innerested in yer li'l test. re: science, i'm not arguing that it hasn't gotten us this far, all i'm saying is it's *only* gotten us this far. it obviously hasn't gotten us far enuff to explain differences heard in cabling.

myself, i also don't have fancy powercords, except for the two that came w/my vansevers unlimiters, one currently (ha-ha!) used for my amps, the other for my sources. not that i don't tink fancy cords wood help my system, but it's not in my budget. until i get the other components where i want 'em (gettin' real close, now), i've felt i shoodn't spend the bucks on powercords. but, stimulated to do cable research, based upon the hoopla over the relatively cheap absolute powercord, i've recently come up w/the source of cabling that tek line uses (http://www.teklineaudio.com/). their powercords, which, at ~$400 retail for a 6' cord, are supposed to be excellent at the price, in their own right. well, i can buy the cabling @ $3.55/ft, get hospital-grade plugs-n-iec's for ~$10-$15 apiece, so i tink isle roll my own for my amps, pre, tuna, & fono-stage. if there's no earth-shattering improvement, i'm not gonna be upset about the minimal inwestment...

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... ;~)

7, no problem if ewe do real research, testing, & inwolvement. woodn't hurt if ewe tried *listening*, too... refusal to try someting yust cuz it doesn't fit into yer pre-conceived notions of what's possible, isn't *real* research, testing, inwolvement. gotta include *all* the data for that...

7, everyone here is still waiting to hear what kinda music ewe listen to, on what equipment, w/what cabling, & what equipment/cabling yure familiar with. *yure* the one keeping it a secret. what's the point? i thought the purpose of this site was to learn by sharing experiences. no one can learn from ewe when ya keep everyting a secret, except yer belief that cabling makes no difference. whether one agrees or disagrees about the worthiness of cabling upgrades, yer beliefs have no meaning w/o examples of how ewe came to them...

702, ewe can make yokes about it all ya want, but it still doesn't make what i say any less true. brulee is right there's potentiual here, for us to learn from yer experience, but up unti now, we have fro ewe zilch, nuttin', nada. total waste of time.

i tink albert is correct. one fact that he fails to mention is that many mfr's actually *do* recommend the purchase of aftermarket power cords. some, however, do not...
