i'm not an audiophile pro so i can't explain what i'm looking for in the exact technical terms, but i'll try.
I really love the Alessandro Ms1i performance, but i want headphones with more detail now. The Ms1is have great bass and acoustics, but i find that the vocals (mids?) are a bit recessed. i want more articulation in that area while keeping the great sound of the lows and highs the MS1is produce.
Looking for full size headphones (don't want IEM's) and i'm open to going for a closed design or open. i'll mostly be using it for home listening, and i do have an apogee duet to act as an amp.
i listen to Electronic music (more towards tycho and talkdemonic instead of dnb or techno)
alternative music (Radiohead)
Rock (Pink Floyd, Tool)
and indie rock, folk music.
as far as the electronic music genre, i'm happy with what the ms1i does, but for everything on down, i would love to see improved detail.
