"I was impressed by this revolutionary stereo amplifier but it became an obsession when I mated three as monoblocks to a trio of Benchmark's DAC3s."
"The AHB2 is deadly silent, musically revealing, surprisingly compact, and quite powerful."
- Kalman Rubinson
"Benchmark has created a long line of DACs (several of which I've purchased) that present recordings with as little embellishment as is possible at their price points. The latest incarnation, the DAC3, is no exception, and excels at presenting the unvarnished truth, as the artist intended."
- Jon Iverson
"Going into this test, based on measuring previous Benchmark products, I expected excellent performance. The benchmark HPA4 shattered even that high bar. It brings such a high performance to the table that leaves no doubt whatsoever about its transparency. No stone has been left unturned to optimize audio performance of this device. Even obscure measurements like ultrasonic interchannel phase shift is nailed."
"And then we have tons of power without messing with balanced cables and such. Plug in any headphone and you are in heaven."
"The preamp performance is even higher still, breaking and shattering any expectation one would have in a lab instrument let alone a consumer hi-fi."
"It goes without saying that the Benchmark HPA4 garners my strongest recommendation for a headphone amplifier and preamplifier. It doesn't get better than this folks."

"I ended up visiting this room more than any other room at the show. I couldn’t help myself; I had to keep coming back for more!"

"It’s ... been a while since I have been this excited about an audio product."
"Audeze LCD-2C, Quad Era-1, Brainwavz Alara, Sennheiser HD650 ..."
"It’s the first time when I have heard the headphones mentioned above to their full potential. In the first minute my jaw dropped ..."
"From my perspective this is the best headphone amplifier I have ever heard. It’s no competition really."
"It’s not cheap, I can give you that. Is it worth it? That is up to each and every one of you, but if you really want the best amplifier out there, an end game amplifier…this is it."
