After Market Power Cables - Gold or Snake Oil?

But my point is that the "why" you might receive may have nothing to do with our claims of a sound difference, so if we are deluded you are merely asking for a rationale so that you can be deluded too.

Redkiwi,
No, when I ask you "why" I am not saying you are deluded, I am just asking if you really know what phenomenon caused the sonic difference you hear. Psycho-acoustic effects, like optical illusions, "feel" like the real thing.
This is in no way the product of "delusion" as clinicly defined. It happens to everyone.
I know this is true because I have experienced it myself.
(the "compressor" story in my last post)!!

I am not trying to be contentious, I would just to like to know why people are hearing what they are hearing.

Checkmate110 - You are correct, the total inductance from the panel is what matters.

M_Cassar - there is one other possible benefit of a power cable and that is filtering. This filtering can be only on the ground wire or the current-carrying wires. Ground-wire filtering makes a lot of sense, since there should not be any AC current on the ground anyway, since this constitutes ground-loop noise. Filtering on the current-carrying wires, hot and neutral is another matter. I personally do not believe in it (and my designs do have hot/neutral filtering), but I suppose some components with poorly designed power supplies could benefit from this. Certainly not amplifiers though.

Oy Mate, my point is simple - I do not know "why" PCs make a difference, but they do. If I gave you a "why", then that does not prove anything. No matter how plausible the "why" I give you, it does not assure you of ANYTHING.

What has a greater chance of being relevant is this. I have heard the difference so many times both between different PCs and between after-market PCs and stock PCs that there is no room for doubt in my mind. Others here will tell you the same. A very few others have said they hear no difference. That is all folks - the rest is up to you to try it for yourself, or not to.

Debates as to "why" will get you nowhere. If you don't believe me then look up the archives and find how your question has been asked here many times before, that many explanations have been put forward, but that this proved nothing to anybody, simply proving my point that we are all none the wiser unless the discussion causes you to try it for yourself.
