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.

Jadem6: Why such hostility? I'm always open to learning, and I try to learn constantly. I recommend it to you, too. I've been away, busy with work, writing, playing music, etc. It's good to have a little free time again.
What's wrong, Dekay? Why would I not want to think or hear? BTW, are you still up for double-blind tests of power cords?
I do them all the time, it's my new life. Where have you been? I don't do judge and jury anymore (just make obvious observations on my own) so, you will have to answer the other questions on your lonesome.
702, is there a site that you actually enjoy? I know you do not care for Audiogon, as you come here only to argue about your silly double blind theory.

Your insistence in continuing with the same tired argument that has been responded to by dozens of Audiogon members, proves your inability to think for yourself. You are either too shallow to accept our challenge to learn, or you care absolutely nothing for music and refuse to invest the time or money required to make it better.

You are a pseudo intellect. You visit here only to engage people in arguments over matters that you have no real passion for. The real drive behind your politics is to prove your mental prowess, boost your ego and enthrall yourself with the attitude of superiority.

It's too bad you cannot channel some of that energy into learning about music and the audio components required to make it better. You could improve your system (if you have one), and possibly even find your life fulfilled for once, possibly even finding happiness.

Of course I could be wrong, you may be so void of all soul, passion, creativity and the ability to grasp a challenging concept, that it would be lost on you. If the latter turns out to be true, then you deserve our pity.
I have had a psychologist friend of mine look at the posts made by 702 here. It is perhaps unfair of me to quote his diagnosis fully, particularly the bits about the kinds of events in his past that might have caused 702's dysfunctional interactions. Sadly we are likely to be the closest friends he has and he knows no other way to get our attention and love. You are right in one thing Albert - it is pity he deserves.
