Benchmark AHB2 Amplifier, opinions and competition

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.  

I don't  see how those speakers could be vertically bi-amped yyzsantabarba there's only one set of binding posts you could use monoblocks.

My Benchmark amp is about two years old. It replaced a First Watt F6.  About a year ago, I purchased a Benchmark LA4. It replaced a Audio by Van Alstine T10 RB tube preamp.  Awesome sound!
