Benchmark AHB2 power amp impressions?


Does anyone have any opinions/info to share about the new Benchmark AHB2 power amp? Do the company's assertions about drastically reducing noise and distortion ring true? Thanks to all.

I purchased enough of the AHB2 amps to tri-amp my speakers, and these are truly world class amps.  

Having an invisible noise floor means you can hear so much more detail that was previously hidden in the background (at loud or even soft volumes).  You can also hear things at low volumes that no other amp I have heard is capable of, and measurements of what this amp can do at the 1 watt and below clearly show it's distortion is the best out there.  Hint: ultra low distortion at 1 watt and below really matter if you want detail at low volumes.

This amp is absolutely fantastic from an engineering and specifications perspective, and the real world listening is the same; it can make hairs on your neck stand up because it can sound that real if the rest of your system can reproduce the required dynamic range with ultra low distortion.

The dynamic range and driver control in my setup is truly unreal.  To be fair, my setup also involves using active XOs that employ FIR filters, and of course I removed the passive XOs from my speakers to achieve the best possible damping factor.  I have all drivers time aligned as well.

That said, I did try several amps in the $1k-3k category in my tri-amp setup, and the Benchmarks are absolutely some of the best amps on the market.  I've shown my system to one dealer that does $100k+ setups and he couldn't believe the sound of my setup.  Google the measurements and read the reviews such as the one Stereophile did.

I totally understand if someone likes the warm sound of tubes though, but if you want to hear exactly what was recorded in ultra high fidelity with the best possible dynamic range, these amps are likely the best option for you.

Since I'm a decent guy, if you are local to Columbia, SC maybe I can let you hear what I'm talking about.  Send me a PM if this is the case because I don't come on here very often...
Thanks for invite. People must love the amp...not may used (or they return them quickly after purchasing). I'm hoping, after new year, to try one in my system. I have to say, my NuForce STA200 is sooo good as I have everything dialed in great. However, the thought of the ultra quiet Benchmark, with my RP-5 tube preamp and ZU omen defs really sounds appealing.
I've had the AHB2 for the past few weeks, and absolutely love it!  Paired it with Hyperion HPS-738s and Dynaudio EX34s.  Dead quiet, wonderful bass control.

I've installed some Neutrik NL2FX connectors on my speaker cables and not sure how much of a difference it makes in comparison to the regular binding posts, but I sure love having the option.  It's a solid connection for sure.

So much impact & clarity for such a small amp.  Thinking about picking up another one in the near future to run as monos.


I would probably buy the actual Benchmark speaker cables. I believe on another forum, a couple said they were quite good.
I have an all Benchmark system - DAC3L > HPA4 pre > 2x AHB2 in bridged mono.

I completely disagree with the comments that the AHB2 is clinical sounding. To me it sounds beautifully balanced and fully capable of reproducing the full range of musical colours and emotions. Notice I say reproducing. The AHB2 is definitely not a coloration machine for injecting flavour, it's an 'as is' device for reproducing whatever is provided by the source. 

I've had 6-7 amplifiers of all types through my system in recent years and have found that amplifiers with 'flavour' eventually become tiresome as the 'thumbprint' is heard on everything that passes through them. I prefer the revealing, chameleon like, character of the AHB2 where the sound changes with the qualities/intricacies of the source. 
I also appreciate these qualities in the ATC monitors I'm using in my system and find the combination musically compelling. YMMV.
