in case i decide to buy an amp later... which cans will make me happy without one and even happier with it, and do amps always make headphones sound better? also, what is better, lower or higher impendance?
it seems so far the ultrasones have been recommended the most and the 990/150's equally, from everything ive read this is my interpretation of things (at least with the beyers).
dt990 - bright, big soundstage all around good when amped?
dt150 - big bass, and analytical since they are studiophones?
dt770 - bass monsters?
dt440 - better for all around listening, sorta groovy feeling?
^^^ please edit and correct me if you please, give me your take. This is just what ive sorta absorbed from the past couple days, i could be way off heh.. could you guys describe each of these describing the bass, mids, and highs for each? with and without an amp?
