Best Amp Martin Logan Summit

Those are some finicky speakers. You are really going to have to audition to get the best fit. I had a listen to these at a friends house with $9k and $10k amps (and less expensive units) & they are difficult to get right.

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.

I jave heard it with VAC Phi Beta. Fantastic. Of course, what is nice for me, maybe a coloured and distorted sound for you.

Have you considered a YBA? In your price range you have too many options to count. Demo, demo, demo. The Passion 600 should be a very go match.

Good luck!

I have Summits, I have tried Krell 300c, DartZeel 108, Mark Levinson 432, Sonic Frontiers Power 3's. Settled with the most musical amp I have ever heard which is my Mcintosh MC2000 with NOS 12AX7's. This combo with the active bass is AWESOME. And I have to say I am a very critical.

I would stay with tubes. Those panels are two good for soild state. Even the best soild state. With good tubes I don't think better music can be made. Just my 2 cents.
