for my $.02...
my parents are impartial to it... mainly because they don't know how much any of it costs
most of my friends are impartial as well. they know that i'm in a different league than they are (they're them bose-addicts), so they give me the stare, then the respect of my opinion which they admit is probably better than that of a bose-lover. A couple, though, gave in. one is spending lots of $$$ on an all around set of minirigs. the other immediately gave in (and i mean immediately) after he auditioned the sr225's at my request. and, of course, i got people to buy an hd580 and a couple hd280's.
my roommate just ignores me
as for those in my dorm building... well, they either don't notice (whew!) or they're just wide-eyed about my setup.... or half of it
