Power cord? Why?

I suppose it would be totally out of bounds at this point to say that I have gone beyond AC power cords, and found that even in straight flat DC power, I can hear differences in the types of chemical compositions of the batteries being used. Not only does the wire matter, but whether there is a Ni-Cad, Lead Acid, Alkaline, or whatever kind of battery being used. I use DC power for most of my system, and have experimented with different battery types, and believe me, they are audibly different. So, is 12v simply 12v, or is there a difference?

Science is to be used to explain why things happen, not to be used to say that they can't happen because the scientist can't measure them. A real scientist would expand his study and abilities to find out why there is a sonic difference, and not stand on previous ideas that cannot explain the phenomenon. Science is learning, not the refusal to learn.

Viridian - the point is that if you cannot measure anything, then your mind may be playing trick on you or you have not gotten to the root-cause of the sonic change. At least if there are measurements that coincide with sonic changes, then theories as to why the changes happen are more feasible. It provides some basis for explanation.

Batteries, like AC power sources have impedance. Some batteries will have lower internal impedance than others. Some will work well during transient current demands and others will not work as well to provide the transient current. There is no surprise here.

But Twl, what about the cases where science CAN explain things, but audiophiles refuse to acknowledge that an explanation exists? I'm alternately amused and offended by people who want to lecture me about what science SHOULD do, while refusing to accept what it has already done.

Bomarc, I have no problem with science explaining things. I like that. What I repeatedly hear, though, is that either there is no scientific reason for cables sounding different, or that we are all imagining it, or both. If there is some other scientific reason that you are alluding to, I am all ears. I have no quarrel with anyone who can show that there is some difference in inductance or capacitance or whatever, and if that is verifiable and useful, then I am all for it. I only say that I hear differences and am willing to use the product that sounds best to me. If I can gain information that will help me to make decisions in bettering my system, I will welcome that. However, I do feel frustrated, as you seem to be. I am frequently under attack for believing something that I can hear making an improvement in my system. Personally, I really don't care if there is some kind of magic dust in there or something. All I care about is that it makes my system sound better. To me, technology is a means to an end, and not an end unto itself. I don't make cables, I listen to them in my system. The details can be up to the manufacturers. What I want is a good sounding system. And whatever it takes to do that, is what I want.

While we frequently disagree on this subject on this forum, I have no quarrel with you personally. I would like to reach some kind of common ground that we could agree on, and maybe that would yield some good. I have a very simple goal, and that is a good sounding system. I assembled a variety of things that sounded good to me, and that is what counted for me. If technical-type people want to boil all the nuts and bolts down to some kind of essence that will help us all understand and decide, that's great. The only part that irritates me is the part where people tell me I can't hear something that I clearly hear, and claim that some "fact" means that I can't be hearing it. If I am misunderstanding your position, then I apologize. It is also frustrating to be on this side, and commonly be told that I am in some sort of "delusion world".
