I had the M3 and it like all others performs better when it synergizes with your other gear. It was as stated reticent in the treble, a bit closed in and a bit slow in my setup. This took away from the excitement of the music it produced. I have to assume it would perform better in other setups. I sold mine. Even the bass in my setup was not what I feel it should have been. The less than sparkling highs seem to be a common thread with this piece. Beautiful integrated however.
