You can make any audiophile claim your system now sounds better by futzing around behind it for a while and claiming that you installed a "polarity aligned non-hertzian oscilation dampener" or whatever but in reality make no alterations other than turning the volume up one notch.

This is a well documented phenomenon, and reproducible with almost 100% accuracy. It turns out that humans are, objectively speaking, tin-eared gits. This expressly includes audiophiles.
