This phenomenon goes beyond theory into the gray areas concerned with human perception. As we know, perception is not tied directly to reality, but is wholly influenced by the constructs of the human mind. To me, the phenomenon behind speaker/power wires making an actual noticeable difference in the performance of an audio system works in the same way homeopathy does. First of all, you absolutely CANNOT convince believers, regardless of the evidence to the contrary, that it makes no difference. Second, since perception is entirely subjective, if you think it works, then that perception provides self-reinforcing comfort.

It has nothing to do with how evolved our ears are. Compared to a dog's, our ears are mediocre at best. What matters is perception and how much the human mind can influence true objective reality -- which really doesn't exist in the first place.
