Benchmark ABH2 amp and full range electrostatics, e.g. CLX or Soundlab

I have read the glowing reviews of the Benchmark ABH2 and have seen that Martin Logan has used these amps at Audio Shows with some of their hybrid speakers.  I would appreciate comments from audiophiles and/or reviewers who have significant experience with the pairing of the ABH2 amp with Martin Logan CLX's and/or Soundlab full range electrostatics.  Thanks in advance.

and like you whether the doubling of output impedance would pose a problem in regards to the very low impedance the CLX has above 8 kilohertz.
Yes and this is why you should get the "correct amp" that has no problem with this loading. And not gamble that bridged AHB2 are going to remain stable and handle the 1ohm loading.
As for tubes with this loading it is also why all the ones I have heard into my ML's have sounded "distant/muted" in the top end, lacking sparkle and air.

Should be fine, but I would not use a "bridged ABH2’s" (mono’ed) into these sort of ESL 1ohm loads, as the stability won’t be as good and the current ability to drive into low impedance will be halved.
If you have two ABH2’s and the speakers have two sets of speaker terminals then you could vertically bi-amp the stereo ones.
