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

I have mono ahb2s and CLX Art. The amps have had no issues with the speaker bridged and also feeding 2 x rel subs. Amps are as transparent and lacking in color as anything I’ve heard. Replaced a luxman M900u which was very warm in comparison.

Thank you for this feedback.  I have Anniversary CLX's and had a concern regarding the ability of  single amp to properly drive these speakers and the higher output impedance of the amps when bridged.  Are you using a Benchmark preamp with these amps? Also do the Benchmarks produce a realistic soundstage in width and depth as well delineation of individual voices and instruments?

I started with a single AHB2 and it had no issues. I only added a second one because a used one kinda fell in my lap and it did bring an additional level of effortlessness that was worthwhile. 

As far as I can tell the Benchmark will simply reproduce whatever it's given and has no definable sound that I can discern. Soundstage width and depth are fully determined by the upstream source and recording not by the amp/pre. Likewise the overall presentation of the sound is determined by the recording and varies drastically. If you're used to components that intentionally inject a signature on the sound this may be hard to appreciate but for me it makes every recording a unique experience and world of fascination. 

I've done a ton of work on upstream components including external clocking in the digital domain and it has revealed every change. I've tried dacs up to $40K and have a similar amount in analog front end (Technics SL1000R / DS Audio Master 1) and so far have not been able to perceive any kind of bottleneck from the Benchmark gear.

I do also use the HPA4 preamp as well and it has a similar level of transparency. The preamp replaced a Luxman C900U.
