Hi Frap. Thanks for the help - I hope Mmccoy realises we are trying to help, not beat him into submission. Good PCs on electrostatic speakers do indeed have a significant effect, in my repeated experience. The standard cords sound as if detail has been smoothed over, there is an upper midrange ringing, and the soundstage shrinks. The ringing problem can be reduced by using RF blocking capsules on the power cord, but it does not improve the other issues.
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.
