Electrostats love tubes (or was it the other way around?) And since these speakers (finally!) have their own ss bass amps, you are free to drive the panels by themselves with a quality tube amp. This is the way it always should have been. I don't know what took Martin Logan so long!
So IMO you should forget ss, and if you can afford Summits, then go for a pair of Class A Triode monoblocks like the Lamm or similar. Anything that puts out around 90 Watts (or more if you can find/afford it) should be fine.
