How loud have you played your M50's. I was really pushing them hard the other day, probobly louder than i ever played them before with 2ch music, and the loder i went the better they sounded. I gotta say my ADCOM amp has power for days. alot of bass too, i thought the sub was on a couple of times but it wasn't. i'm thinking about throwing a party as an excuse to blast my M50's, Heineken any one?
