Dust Settled Consensus- is the Benchmark AHB2 an Audiophile Amplifier?


As the dust settles on the time the when the Benchmark AHB2 amplifier was a hot topic in the audio world, what is the long term consensus about this amplifier?  

Has it become a mainstay in the audiophile community?

I enjoy AHB2, but Paul Seydor in Absolute Sound review of AHB2,suggested it is not an audiophile amplifier:

Because accuracy allied to absolutely reliable performance is the goal of all the Benchmarks, they are not products that tend to attract cults or other sorts of starry-eyed enthusiasts, wholly lacking any of the quirks, foibles, idiosyncrasies, sonic flavorings, euphonic distortions, and so on that characterize the objects of most audio cults. Professionals buy Benchmark because they know the products work and are reliable and accurate—indeed, reference caliber. Music lovers buy them because they are neutral and accurate and thus reproduce the tonal character of voices and instruments correctly (and also, I presume, because they are reasonably priced, most musicians, like most other people, being typically not wealthy). But audiophiles? Well, the longer I’m in this racket, the less I sometimes think I understand what audiophiles really want except that a lot of dallying about with components, equipment swapping, and coloration matching seems to be what amuses them. I’m not sure I can in good conscience recommend this amplifier to them as I am not sure they are in search of what it offers: a precision instrument designed to perform the precisely defined task of reproducing music and sound accurately, which it does essentially to perfection. But to anyone else, the AHB2 gets as high, enthusiastic, and confident a thumbs up as my arm is capable of reaching.

@yyzsantabarbara Thiel CS3.7 minimum impedance is in order of 2.5ohm (2.8ohm specified, 2.4ohm measured by Stereophile).  Driving it by AHB2 in bridged/mono mode is equivalent to driving 1.25ohm speaker in stereo mode.  AHB2 is not rated for that and not too many amps can do that.

@ricevs Many claim that amps like AHB2 reduce harmonics. I don’t know how it is possible if amp has flat amplitude and phase response in audio band.
Adding even harmonics to create "warm" sound or bit of distortion to create illusion of dynamics seems to be what people are looking for. Warmth of the sound is assumed a virtue. Do you still hear clarinet (only odd harmonics) when you add even harmonics? Do you hear real piano sound when you add even harmonics that beat with stretched piano overtones? One person claimed that Benchmark DAC plays instruments separately while he preferred them all together (sound blob?). Another person asked how to make sound warmer and less detailed (I recommended blanket over speakers). Perhaps we need to learn to listen. We know that sound at the concert is different but at home we follow sound that we got used to. I took me a while to get used to clarity of the Benchmark DAC.
