Have you looked at the new Carver mono blocks? The first generation Black Beauty 305's uses KT-120's (approx 350 watts into the 4 ohm Maggies) and there is also the Cherry 180's which is approx 225 watts into 4 ohms.
I have the Magnepan 20.7's and have tried a lot of different power amps and so far nothing is close to the Black Beauty's performance. There is no question in my mind that the Black Beauty's seriously out perform several 1,000 watt solid state mono blocks that I have tried. With Maggies it is just not all about "watts".
The Black Beauty's do not break a sweat driving my 20.7's no matter how loudly I play music! Check Audiogon, AudioMart, and WattSpot for a nice used pair of the Black Beauty's or even the Cherry 180's; they will drive your Maggies like you have never heard!
