comparing with m2- M2 even though is priced higher, there's something quite not right about it....its a placement or positional issue..it dosen't throw out sonic cues pin pointing which part of the room a particular instrument is placed in...... it sounds small as in music playing in a cramped congested room. . there's no sense of space ....i have discussed this with esanthosh a couple of times too...
in terms of bass response, m2 has a similar soft bass impact like the gr02 but its not quite as airy as gr02. midrange clarity seems a tad better on the m2 but the lack of soundstage depth kills the listening pleasure(at least for me) . separation is better on the gr02 . Again i prefer the GR02 more than my m2's .
