Thoughts on mating ML ESL 11 A's to a butler TDB 2250 hybrid amp

I keep poking around and discovered Manley 250 monos any thoughts on this amp paired to Martin Logan ESL11A using a Linn DSM as a source and pre amp

I would personally steer away from tube amplifiers with ML.  While I'm sure those Manley monos are very nice, they explicitly state the optimum speaker impedance is 5 ohm and the output impedance is 0.538 ohm.  The ML panels are very capacitive and the minimum impedance is 0.6 ohm at 20 kHz, so probably not a good match.  If you crave the tube sound I would look at a hybrid design, since you already have your source/pre.  For what its worth I have the predecessor to your ESL11A (Montis).  I power them with Pass INT-150.  I think Pass amplification works well with ML.  I'm sure there are many other (less expensive) alternatives that would work as well.

I heard Butler amps a few years back and thought they were very good. Now the Manley 250's would be in a different class altogether IMO.Since Audiotroy doesn't sell Butler anymore I could have guessed what he would have said! Oh well I'm sure you can read into his posts.

I definitely agree with jtucker on  the Manleys, the 11As are rated at 4 ohm average, dipping below 1 ohm, so don't thinks it's a good match.
