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.

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.
Well now I feel bad. When it's looked at that way Red, it all makes sense. That explains why he continues to let us in on some of his career success, he wants us to be impressed and become his friend.

O.K. 7, I'm sorry. Please tell me more about your self so I have a better understanding of you. Maybe you could let me know which shows you've worked on. Your in the business, what studio do you work out of? You must have met some fascinating people along the way. Oh and one last question, why do you insist that power cords make no difference when they clearly do?

Hope to hear more about you soon,
J.D.
