Dust Settled Consensus- is the Benchmark AHB2 an Audiophile Amplifier?


As the dust settles on the time the when the Benchmark AHB2 amplifier was a hot topic in the audio world, what is the long term consensus about this amplifier?  

Has it become a mainstay in the audiophile community?

@decooney The Benchmark DAC3B | RAAL-Requisite VM-1a tube headphone amp | RAAL-Requisite SR1a earphones or CA-1a headphones are an incredible combo. The DA3B is magic with this headphone amp. Other warmer DACs, like my Musetec 005 DAC, do not match well with the 7 tubes in this amazing headphone amp.

I am trying to recreate the same level of sound with a future 2-channel system in a decent sized room. It is going to cost me some money to do so but the above sound is the benchmark that needs to be surpassed, and I do not mean the AHB2.

My office system with the KEF LS50 meta and the AHB2 stuff cannot approach the level of sound as the RAAL VM-1a. Even if I spent $100K more on gear for my office system. Room acoustics dictate that it will not sound as good as the SR1a earphones. Now in a bigger room I believe I can get better than the VM-1a + SR1a.

Stereophile will be reviewing the VM-1a and SR1a and likely going to say the same as me.

  • AHB2 monos | LA4 preamp | SR1a earphone | RAAL amp adapter box | Musetec 005 DAC is very good. Though not as good as the VM-1a + Benchmark DAC3B.
  • AHB2 monos | LA4 preamp | SR1a earphone | RAAL amp adapter box | Benchmark DAC3B is awful.

 

The Peachtree Nova 150 is not even anything today. The latest GaN amps from Peachtree are another level. The Peachtree GaN 400 is the exact same amp as the LSA Voyager.....same boards inside a different box. You heard the Voyager stock and modded.....so you know how good that is. The GaN 1 is a completely different thing. It is a fully digital input class D amp.....It eliminates your DAC, your preamp, your analog interconnects, all forms of feedback. This is the revolution we have all wanted. No more heavy boxes. This amp will drive your new Kefs like crazy....200 watts a channel. Of course, the execution in the GaN 1 is still not super serious. You heard what my mods did to the Voyager......even more could be done to this $2000 amp. The glory of great sound for little money. We need to rejoice! 30 day money back trial. You need a great digital source.....(not the Blue sound) for best sound....and of course, a great digital cable, great footers, mass damped weight on top.....and Inverter power so you are off the grid. Such a system will simply blow your mind.

It seems clear that the AHB2 is system dependent.  In my system it is perfection.  
However, I believe all those who find it terrible.  Their ears are not deceiving them.

 

@ricevs I do remember reading about this GAN 1 amp now. Now that you have compared it to the Voyager, I will believe what you say. Ric's mod of the Voyager was great. It was almost like the AHB2 for my ears, with more power than the stereo AHB2. Since I had the AHB2 I decided to sell the Voyager.

BTW - the AHB2 monos (what I use) are close to 400 watts (or maybe 500) without increased distortion as you usually see when you switch a stereo amp to mono.

 

The GaN 400 is the same as the Voyager......the GaN 1 is the new digital input only amp. The Kef Blade 2 Meta’s do not have that low of impedance and are 87db sensitive, so 200 watts will get you at least 107db. How loud do you listen?
