Benchmark AHB2 amplifier - what to expect?

My current amplifier, driven by Benchmark DAC3 HGC, is Rowland model 102.  It is basically couple of Icepower 200ASC modules packed into resonance free heavy case, with additional input differential amp THAT1200.  These modules were used in many small class D amps, including Bel Canto S300 and M300.  I feel that Benchmark AHB2 might be a good choice for few reasons:

- It matches my Benchmark DAC3 (electrically and physically) 
- It has neutral sound, that I like, with very low noise floor (according to reviews)
- It could possibly extend trebles a little more  (trebles are slightly veiled now).

My speakers are Hyperion Sound HPS-938, (a giant killer), but not too many people are familiar with them since company went bankrupt few years ago.  They tend to sound warm (soft dome tweeter), with wonderful midrange.

I'm looking for anyone familiar with AHB2 and class D amps.  I found favorable review of AHB2 vs NAD M22, but it might not apply to my situation since M22 is based on different modules (Hypex).  My birthday is coming in a month and I could buy myself a present.  I will be grateful for any comments.

Thanks, Randy. I forgot about their 30 day trial policy. Now, it will take some skills to convince my wife it is absolutely necessary.

It's a very good choice I'd say and one I would consider as well.   Have heard it in BEnchmark room at shows with DAC 3 and liked it very much.

Mapman, thanks.  I know it was a while ago, but how would you assess trebles?  Was it an "airy" presentation?  My Rowland is a little bit on the darkish side according to one editorial review.  AHB2 might be good step-up for me from entry level class D, not to mention that is also very efficient with idle power of only 20W total and 0.5W at standby.  I also like the fact that it utilizes quiet SMPS  since it is efficient, plus line/load regulated and not sensitive to DC on mains (no transformer buzzing etc).

Kijanki my recollection is the treble was very good and I did not notice any issues with high frequency "air".

I suspect the Benchmark or alternately many good quality newer generation quality Class D amps in the last few years like those from Bel Canto can be a step up from Icepower of prior generations, in particular when it comes to high frequency "air". I have a Bel Canto C5i digital integrated in my second system that supports that theory.
