I really like my T50RP's for this. Nice bottom end bloom and enough detail to pick apart snappy electronic tones, clicks, pops, etc. They could use an amp, but you can get away w/o one, imo. They're well under your limit after modification, though, so it might be enough to buy a headamp in the used market on the cheap, or even an old receiver from Goodwill, a garage sale, what have you.
