Benchmark AHB2 Amplifier, opinions and competition

Benchmark has been "sold Out" of the AHB2 for a while. Just curious if a new version is coming pretty soon. 

I found it interesting the amp is out of stock thru Benchmark direct. Back ordered at B&H. Maybe some issue with part shortages or manufacturing plant. One would think that if a new version was close, one would hear something at recent audio shows

I may just have to try one and be done with it

Music direct backordered as well

Bringing this thread up due to PS Audio going direct, this, no more deep dealer discounts. I was hoping to have funds for the PSA BHK 250 by the end of the year. However, that has changed and now there’s only 2 weeks left for dealer orders. My preamp is the BHK pre. Before looking at the BHK 250 I was zero in on the following amps to replace my NuForce STA200:

1. ABH2

2. Carver 275

3. Rogue Stereo 100

4. Mac MC275 ( I would have to save until the end of the year)

5. PrimaLuna 

Looks like back at square one. However, I could possibly swing PSA class D M700 monos while I can still get a discount. 

I know the above amps all have have different characteristics. I’m running ZU Omen Defs ( I’ve auditioned small watt tube amps in my system...they Peter out at high volumes). 

Im wondering how the M700’s would compare to a single ABH2?

Thanks. The Nuforce has more than enough power. Sounds great, just lacks a bit of finesse imo.
