Thanks Jwg1749

theoretically speaking, isn't the powered sub in the Monits supposed to make the life of Devialet easier since now all its power will be purely for the panel?

True, the powered sub does make things a bit easier for the amp, however providing sufficient watts to a big bass unit isn't a problem for a Devialet. The problem with the Montis is that towards the top of the frequency range the impedance drops to about 0.5 Ohms. ESLs act as capacitors: that's to say they require voltage above all. Most solid state amps, faced with a capacitor that has an impedance that low, will not be able to offer sufficient voltage, and the consequence will be that the amp's protection circuits will cut in, resulting in distortion. So the theory is that a solid state amp needs to provide huge voltages in order to drive an ESL panel properly.

The Monits i auditioned on McIntosh tube amps and was very impressed with the sound quality and how open the sound was.

What you've experienced here is that tube amps roll off at high frequencies, and so the problem of HF distortion doesn't occur.

how do u find ur Montis on D200?

I think the Montis are very good with the D200. I just wonder if they might not be even better with an amp specially designed to drive them.

There's lots of info on amplification over on the Martin Logan Owners Forum.
