I have owned Maggies, various models since 1982, and this is what I have found, albeit limited amplifier experience, various integrateds, GAS ampzilla, Adcom, Hafler, and various Classe' models. The bass panels require a good quality amp with decent current upon demand for that special maggie magic. This does not equate to watts. However, that can also depend upon the size of your room. Remember, although they are not the most efficiant speaker their load is not too terribly difficult to manage. I believe they are 4 ohms across the board. In conclusion, I would recomend high current solid state, unless you can afford the higher powered CJ's or ARC's. Therefore, I would have to recommend Classe', Bryston, or Aragon. Finally, watts are only as important as your room size and listening habits. If you do have to spring for lower price solid state, ie., Rotel, Adcom, NAD place a lower value fuse in line with the tweeters ribbon. These amps seem to stress the tweeters more and replacing the ribbons can be costly. Although, Magnapan is very good about repairs. However, I would recommend the prior amps. They truely bring out the best in Maggie. Does anyone use McCormick's amps with their Maggies? I have some experience with the .5 delux. However, I never listen to them paired with Maggie. One last suggestion. Although the BK140's sound good with certain speakers, they are not a good match with maggie. Enjoy!
