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.

Look whos telling who what. Stevemj, when you have half the knowledge not to mention the equipment of Albertporter maybe someone will listen to you. Please tell me, are you saying Albertporter is hearing something that isnt there? Were you there? Is he lying to us? Your gas pump analogy is pathetic. So are your posts.
702, are you not also making a boastful claim when you are telling others that PCs do not make a difference. Thats a boastful claim to make about others that you know nothing about. I have no idea why one PC can sound different than another PC because unlike you I am technicality ignorant.
Do you believe that Jcbtubes, myself and others are hearing things that are not really there? Do you believe that we like spending this kind of money for PCs that are no better than a standard Beldon PC? Am I really fooling myself? I would offer you a PC that IMO makes a huge difference but I get the feeling you have a need to be right more than a need to make your system sound better. If I am wrong just let me know and I will loan you a FIM PC for two weeks. BTW 702, I picked up a couple of CDs that you recommended. They were very good, thanks.
Hi 702, unlike me you seem to have a good knowledge of electronics and why things should or should not work. I believe that most PC,IC, speaker cable, ETC have a sound, coloration or whatever you want to call it. Maybe thats part of our problem. When I put something new in my system, I expect a change in sound. You are coming from a different point of view. I guess you don't expect a change in sound with PCs. Maybe we both have preconceived ideas. As far as double blind testing, I have tried and failed but that does not mean PCs are not a benefit. It just means I failed. I could give reasons why double blind testing doesn't work for me but it would sound like I am making excuses.
I don't think you are a pseudo intellect, I think our background in audio sometimes gets in our way. Even though I failed blind testing, at least I gave it a try. Have you or will you give a PC a try? I have one you can borrow for a week or two. I took the PC challenge and failed but it doesn't change the fact that PCs can be a valuable upgrade. I challenge you to try my PC. With this challenge there is no failure. You hear a difference or you don't.
Hang in there 702, I like the way you stand up for yourself. I agree with Jhunter, I think you are getting less respect than deserved.
Hi 702, could you define "proper double-blind test" for me. After hearing the ICs and speaker cable from the Sakura OTA kit I agree with 702 that the fancy special cables arent necessarily better. In fact I have yet to hear anything as good as the OTA wire. I can't help but think that I have been getting shafted by the wire MFG. for all these years. But no more. When $12,000 worth of wire gets spanked by $300 worth of OTA wire it gets me a little pissed. Live and learn I guess.
Hey Dekay, you gonna try making a PC out of the OTA? I'll be more than happy to go in on it again.
