Listened to the M3 extensively when I was auditioning for a new amp around 12 months ago. It was very impressive driving some PMC speakers (OB 1's, I think) generating a wide soundstage with solid bass and good integration. I ended up preferring the Musical Fidelity A5 by a very slim margin - seemed slightly more neutral and more dynamic than the NAD. Perhaps the extra watts in the MF played their part. But I remained very impressed with the NAD.
