Albert - This isn't personal. I like talking about hifi related things. I don't get upset if someone says that their line cord makes a huge difference. I find it interesting. I don't judge people by whether they use expensive line cords or not. I have friends with whom I disagree about important things. Like you, I am just expressing my opinion. I don't like fighting and I take care not to write anything that sounds personal. I state an opinion and try to back it up with some information. I thought you might find the line cord voltage numbers interesting. It wasn't written with the intent to agravating you or with the expectation that you were going to read it and cry out "MY GOD, how could I have been so wrong!?"... And, I'm sure that if I had a chance to hear your system I would agree that it sounded damn good.
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.
