Dude, the argument here is exactly the one between those who accept scientific blind tests as the main practical window to The Truth(TM) and the fools that do not, so they can justify their hi-fi equipment fetishism. I use silver wire and Auricaps and Caddock MK132 resistors, but at least I don't pretend that I could actually hear a difference (nor would most of the self-proclaimed golden ears; if you come across them in real life, it's always fun to challenge them to a blind test and embarass them
).
