My amps for comparison include an Adcom 555II, a pair of Classe DR9s bridged and not and a pair of Benchmark AHB2s bridged and not. I do not find the Adcom very musical and use it mostly to drive speakers under test. I like the Classe, but the AHB is my go-to amp. It drives the CS2.2s to beyond my loudness tolerance. Its ultra sensitive overload lights tell me when I'm pushing it, which is almost never. I'd call it just the facts, and all of them, more so than the rebuilt and optimized Classe pair. The ABs are class H with a patented THX topology where the class H regulated power supply drives small class A output stages with feed-forward distortion correction. It got class A from Absolute Sound, and seemingly no cred in the hi fi community. I love 'em.

BTW: Benchmark's designer John Siau reviewed the XO schematics and specs and fed back the following:
CS7.2 stereo or bridged, CS5, 3.7, 3.6, 2.4 stereo mode only. That said, I use bridged nearly exclusively without problems. Seems that class H amps hit a hard wall at high current into low impedances. As I've said, I sometimes see flicker, but have never shut one down. 

@tomthiel  I was reading a lot of posts all over the internet on Benchmark because I am currently buying some of their gear, including a couple of AHB2's. From what I read, I think the AHB2 gets a lot of respect in the HiFi community. Some people do not like it saying it is too dry for their tastes. Personally, I do not feel that way and love it (I owned it before).

Today, I was speaking with Mike Siau (maybe the son of John) of Benchmark on some issue with my HPA4 preamp. An incredible sounding unit which I am now wondering if I should buy a second unit. There was some minor issue with something and he did some somersaults to make sure things would get resolved ASAP without me missing a second of music. I feel good about supporting companies like this.

Thank you all for your comments and recommendations on my recent posting. I will be following up.

Pass Int-250 is a perfect match for CS 3.7s juste like the Diablo 300.
