wow didn't think my PS1000 comments would start such a huge debate, i feel bad. anyways umm i just sent the return request to crutchfield so i can ship them sometime this week.
i tried to like them alot, but i just found them too bright for me and for the money, not suitable for as wide variety of music as i wished. they seem to be like 325is but just more U shaped with bigger soundstage.
i still am a grado fan, and do love grados, my favorite by far being the RS1i. i previously owned an RS1i that was in an RS1 assembly. it failed and i got it repaired and replaced with RS1i drivers, so it still had the old cups with the buttons and the older cable which was thinner and longer than the newer ones. i really miss it, its a really good sounding headphone, great midrange and beautiful warmth and engagement.
i plan on re-buying a pair soon. maybe one day, i'll get lucky and come across the HP1000 or something too.
