I would opt for a Hybrid like a Moscode 600 @300w per channel in 8 ohms. The Moscode tubes/mosfet output 150w/chan 9 ohms and I believe they double in 4. If you find one with the George Kaye mods Kudos for you. Mates well with many preamps. Very quiet and reliable too.
They make Electrostatic and Planars sound wonderful. Excellent bass too.
A very robust subwoofer will help them tremendously. If set up properly they let the amp
push the Maggies and the sub takes over from there. There are crossovers available to help you too. Tom Tutay custom makes tube crossovers for the 20.1's and I think the 3.6's too.
