The AHB2 is not biased into class A in the sense you mean. It's a feedforward/feedback nested design with extremely low distortion, and very neutral sounding.Can't lose either way as both are overkill, but which one is biased more heavily into class A? That's the one I'd think might sound best of those two.
Nopefor the klipsch, I would certainly be looking at toobe power. Maybe even SET toobe power. The klipsch do not show their magic very well with sand power (SS), they come alive when driven by the little glass bottles.
That's why I wan't both.Nope
You have not heard them with quality class A SS.
And all the guys that are selling or have sold their AHB2 say the same about them.

Oddly enough I bought my first AHB2 from someone who definitely thought it was meh. I added a second unit and use them in dual mono.And all the guys that are selling or have sold their AHB2 say the same about them.

I have heard this about the non “+” versionsThey may like colorations. In comparison to the AHB2, the A23 sounded dull, diffused and homogenous to me.
And this was Stereophile’s conclusion when comparing the A21+ and the AHB2. That head to head the A21+ won but when the AHB2 was used as a monoblock, the pair beat the A21+Oddly enough I bought my first AHB2 from someone who definitely thought it was meh.

It just so happens that he lives a few miles from me, and we have subsequently become good friends. To his ears the dual AHB2s in my system are a revelation, and he attributes it to having been a single stereo unit versus dual mono.

But I will conclude that both are most likely at the top of the food chain in that price bracket.

Or... a pair of Outlaw 2220 mono blocks ( But is not recognized as Audiophile)
Above 90db?At 90W into 8 ohms in the stereo mode it's pretty underpowered for many systems. That was my issue with it. I'd often have the clip indicators flashing as I like to listen at realistic levels, but at essentially 4x that as dual mono that has never been an issue, and there's an ineffable sense of ease that seemed to be lacking before.
Average about 85-87, peaks in the upper 90s to low 100s.. The loudness that I hear (and measure) at symphony performances in my preferred seating position.Above 90db?
