Many times the power cord has made no difference in my system. If I were somehow brainwashed into believing in the placebo, I would think I heard the difference all the time. But I don't. In my system, the differences are most apparent on my preamp and TV. I've tried different cords on everything else and they don't make too much of a difference.
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.
