It's great to hear how satisfied you are with the M200s. I bought five of them on a special pricing/shipping deal. It is probably overkill for my surrounds (Paradigm Atoms) but for the other three (Dynaudios) they are perfect! The Dynaudios are not very efficient, but you wouldn't know it. The M200s have plenty of reserve power and are extremely quiet during quiet moments in the music and movies. They seem to be a well kept secret.
