Well, somebody's investing more than a little time on the forum. ;o)

One thing that I've never seen done, and I bet would be more revealing is instead of testing wires individually with a resistive load, to test them with a variety of speakers and see if there isn't just some kind of synergistic thing going on. My guess is that something interesting would show up, just as it's quite obvious that amps with nearly identical specs can sound better/worse with different speakers. I think it's one of the requirement of a scientist, or skeptic for that matter, is to keep an open mind.
