B rodgers - think of all the possibilities of low watt tube amp and SET amps you could run now. Forgot the Maggies (subjective), which require big power. Looks like you just took a serious short but in the right direction. I've never owned Maggies, but heard the MMG's and 3.6's. I have owned my share of Logans, a pair Quads, and Carver Amazing Speakers. They are fun but big, power hungry, and may not have the amazing focus of a single driver. Of course it's all about tradeoffs, but the high efficiency thing is an entire different world that begs for exploration. Happy listening! Jeff
