Benchmark AHB2 Amplifier, opinions and competition

My recent amp ownership has been Audio Research Ref 75 -> Luxman M900U -> Benchmark AHB2 -> Benchmark AHB2 Monos.

The Benchmark will not add bloom or warmth to the sound, in fact the entire point of the design is to not sound like anything and just get out of the way, i.e. to be transparent. To me it achieves that as well as anything I've heard.

The downside of that is that if you have problems upstream from the amp it's not going to do anything to hide them and will clearly show you what all your upstream components actually sound like.

If you want the amp to color the sound with bloom then you either need to stick with tubes or maybe try a warm and colored solid state amp like Luxman. The Luxman adds bloom but it's not the same as what you get with tubes and sounds more artificial to me. 

Bump for any more thoughts?

Benchmark is selling them as fast as they make them, along with the new preamp(s). There is a 3 week waiting period to get it. When I got mine a few years ago (not much people knew about it) there was no wait..

Just curious if the following speaker can be vertically bi-amped? There is a photo of the back of the speaker on the link below.

Recently researching for a new amplifier I read a long involved thread about the AHB2 that included a lot of technical discussion and some subjective comments about the sound quality.  
The AHB2 made my short list but I ultimately went in a different direction.  
The people that did not care for them had a common theme- lack of dynamics and excitement.  
Some people that liked the amp overall also thought that dynamics were not its strong point.  
FWIW.
