"Ever since Benchmark released the DAC2 Series a few years ago, the D/A’s measured performance, ultra-accurate smooth ESS-chip audio delivery has made, it, er, the Benchmark of D/A converters. Every DAC I get in for review, I always compare to the Benchmark."
"The primary difference from other DAC2 models is the inclusion of balanced XLR AES/EBU input which makes it more compatible with professional equipment and high-end audiophile gear, and the dual stereo buss output."
"The dynamics of a Benchmark DAC2 Series converter is hard to match."
"The DAC2-DX’s headphone amp is robust enough to handle power hungry AKG phones, such as the brilliant AKG-K803, or any ‘phone set you want to connect to it."
"If you like a clean, transparent, yet smooth and detailed D/A converter for your home pro (or larger separate pro facility) or hobbyist studio, the DAC2-DX should be on your short list of DACs to consider."
"I cannot emphasize enough the DAC2's sound quality. If your only experience has been with the old DAC1 Series, you are in for a treat. The DAC2 blows it away in terms of listenability. Significantly smoother, especially with Pop music. Like the DAC2-HGC, the DAC2-DX receives our Stellar Sound Award and an 2015 EAN Product of The Year Award nod in the home recording studio category."

"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."
