I am using my M2i's as surrounds for HT setup, with M50's as the mains, and a VP100 centre. Based my decision on some advice from Marc at the AUdioshop, as Marc thought the M2i's are a better match with the M50's than M3's. From my casual listening, I think the M2's would make a good HT set-up all by themselves as long as your room isn't to big. Hmmmm......wonder if I could use 6 Mzero's as a HT setup for the bedroom......neat idea!
