Actually, I've never really got a chance to ask this in the other thread, but what is it that you guys want from the M-100? Better bass performance? Overall higher quality sound? Better highs?
For me, I just want an M-80 with greater bass quantity without sacrificing on the detail. As I prefer to listen on my LP2s to my M-80s (chiefly due to the comfort of the former), the M-100 pretty much has that covered. I think a larger M-80 with the same general sound signature with better bass is pretty much what I'm looking for.
For me it's a bit more bass with great texture and punch and better extension in the highs which is from the little I gathered about its sound is what's been added. :P
