Vikings22,
Just for the additional info, I had the ADCOM 7700 driving Dynaudios (4 ohms at best) in front and Paradigm surrounds. I tried the M200s for all channels and liked them better, by a small margin. I now have 5 M200s and they drive these inefficient speakers very well. I sold the 7700 and would buy the M200s again in a second, I like them taht much. Maybe 2 more for 7.1? Good luck!
