For the record my "pans" are run using a 990 and a 7500 amp, although I think the 2160 could run them pretty well. The maggies need a lot of power to generate good bass which is why I have a sub with them just to relieve some of the load from the 7500, even though the wife rarely lets me push them hard. I don't have a 2160 myself, I just keep up with the reviews and threads here on the site. If I were in the market for a stereo receiver I would probably go with the 2160.
