DAC3 HGC - "Expansive soundstage populated with nicely layered instrumentation."
"Tonally things are well balanced, with no part of the frequency range gaining undue prominence. This is coupled to a good dose of refinement, so any aggressive tendencies in recordings, while revealed, are never overemphasised."
"Like all the best products, the Benchmark manages the difficult feat of stepping out of the limelight and letting the music take centre stage."
"These results remain unchanged whether we use the Benchmark as a conventional line-level DAC or as a headphone amp. It is consistent regardless of set-up used, which is a testament to the precise way the company has developed this product."
"The initials HGC in the product name stand for Hybrid Gain Control. The volume control uses a clever design that works in both analogue and digital domains separately."
"Digital signals are governed by a 32-bit dithered volume control, while analogue streams aren’t touched by the processing but remain in their native state throughout the product."
"Benchmark’s work with the Hybrid Gain Control seems to have resulted in a lovely, transparent performance that, if anything, sounds even more impressive than the number-crunching section."
"There’s a high degree of transparency here, and a fluidity of dynamics few rivals can match."
"The Benchmark ... lacks any hint of luxury. It reminds us more of lab equipment than premium hi-fi ... but give it a little time to prove itself and you’ll find it’s an impressively capable unit – we can’t think of an alternative that does so much so well."
- What Hi*Fi?
"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."
