The point seems to me to be to try and prove an effect really exists before trying to explain what causes it. People should start by offering proof that cables really do sound different before launching into putative explanations of what causes the alleged difference. That proof has never been offered. "I use my ears" proves nothing. The first person to prove they can consistently identify differences between electrically identical cables will be a huge audio celebrity, free to cherry-pick any equipment they like in exchange for their endorsement. Come on, why aren't any of you up for that, then?

Blimey Dino, you really have a downer on science old chap. It's a form of knowledge, therefore A Good Thing I would imagine (the social uses it's put to is a different question).
