I currently have a pair of Shure E2C's. I like the sound, and I'm driving them through my iTouch 2G. I'm planning on picking up a Clip+ and a E7 or E11 so I can play my .flac library on the go.
What I'm wondering is if I'd get a huge sound increase from switching to RE0's or Grado SR80i's, or something along .
I'm not a basshead, and I have fairly eclectic tastes in music. Mumford and Sons, Daft Punk, Prokofiev, Frank Sinatra, Napalm Death, etc. I like clarity and an open soundstage. I really don't mind wearing full-size headphones in public, either. I heard the AD700 has a fantastic soundstage, so, should I look into that?
Budget: $100, $120 absolute max.
