I just want to report I took out all my good power cords and located the power cords supplied by the manufacturer for each piece of gear I had, and put them in. I then let them burn-in for three days. The sound was horrid - excruciating amounts of grain, hardness, thinness. If all you wanted from a high end system was power and attack then you might have liked it. But if you wanted Ella's voice to sound like Ella, you would stop listening and go out and listen to Josephine Bloggs at the local Jazz Joint. I put the good stuff back and there it shall stay. That is my sole contribution to this post. Since the object of our hobby is enjoyment of music, the only meaningful dialogue here for me is how to improve this enjoyment. All else is RHUBARB!
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.
