"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."

"If you are looking for a preamplifier/headphone amplifier that you can live with happily for a long time, you should consider the Benchmark HPA4 at the top of your must-audition list."
"The HPA4 combined with the Benchmark AHB2 power amplifier ranks as the quietest rig I've heard (or not heard)."
"Even with the gain up to full with no signal, there is no hiss, hum, or buzz, even when I placed my ears within a in inch of the drivers on 89 dB sensitive loudspeakers."
"As a headphone amplifier, the HPA4 was first rate. Whether it was my most power-hungry headphones, which currently are the new Abyss Diana Phi, or my most sensitive IERs, such as the Empire Ears Phantoms, there was no added noise or lack of adequate gain."
"The Benchmark HPA4 exhibits virtually no noise, whether employed as a stereo preamp or headphone amplifier, and his highly transparent, with no audible colorations."

"Today, is a very special day for me, since I believe I am hearing the best overall performance out of my headphones."
"The distance performance-wise between HPA4 and my second-best headphone amp is Night and Day!"
"This headphone amplifier and line pre-amplifier receives my highest recommendation and scores the highest rank in my book."
"It spoiled me so much, that for the past 3 days I’m waking up at 5 A.M. so I can listen, tap my feet and head-bang just a little bit more. I for one, started saving for one, I’m sorry but I can’t go back to regular amps."
"Without a doubt Benchmark HPA4 is an end-game, top of the line headphone amp – it’s The One to rule them All."

"In the past decade, Benchmark consumer products, especially its digital-to-analogue converters, have achieved acclaim for ultra-low distortion and clean sound."
"While the company is very strongly engineering-oriented, it maintains that listening tests are critical to product development."
"The HPA4 is exceptionally good at presenting a layered, dynamic yet relaxed sound."
"The instruments not only are clearly differentiated but also sound fully rendered, as live instruments do."
"I wish the review sample didn’t have to go back."

"I use them as mono blocks due to my power hungry speakers."
"I hear clarity, precision and an openness in the treble that I haven't heard in my speakers before."
"The HPA4 line and headphone preamp and the power amps are made for each other..."

"I thought the HPA4 sounded as good as any headphone amp I’ve heard for dynamic headphones, and it might be the best of the lot ..."
"The HPA4 is exceptionally good at presenting a layered, dynamic, yet relaxed sound. You can hear these rich results on, for example, Eliza Gilkyson’s Hard Times in Babylon (Red House), where the instruments not only are clearly differentiated but also sound fully rendered, as live instruments do. You also can hear the overtones of each instrument as they decay, which makes them sound more real."
"... wish the review sample didn’t have to go back."

"Aleksandar Radisavljevic used this American amplifier as his reference during R&D of the Raal Requisite SR1a earfield monitors(tm)."
"He's tried ... Bryston, Pass, Krell, McIntosh, Classe and more ... to him and on his own recordings, the AHB2 still sounds the most like live music."
"With Product of the Year 2014-2017 awards from various high-profile publications, our Benchmark amplifier has been comprehensively covered many many moons ago - on standard loudspeakers. But nobody yet thought to review it on headphones."

"An immaculate all-analogue design, the aptly named Benchmark is both technically and sonically as good as it gets."
"The headphone section, with its choice of 6.35 mm stereo or four-pin balanced XLR connectors ... really impresses with a smooth signal delivery."
"While on the one hand it can rock out when it needs to – its prodigious output means it can give as much power as your headphones can take – its sheer impact, openness and vivacity is jaw-dropping."

For 2018, Everything Audio Network has selected just one product for the honor of "Product of the Year". That product is the Benchmark HPA4 headphone/line amplifier.
"One of the most transparent audio products I have ever heard at any price"
"Marvelously open and clean"

"Speaking of reference gear, few names in high-end audio are so closely attached to the reference sound as Benchmark."
"Their fantastic HPA4 reference amplifier could be found at booths throughout the show."
"This year, Benchmark was introducing its new DAC3 B."
"I spent some time playing around with the Benchmark pieces, and they really have a high quality pro-audio-like build to them. They're the polar opposite of some of these more DIY-feeling boutique amps and DACs out there – Benchmark has a very professional level of finish on it."

"Benchmark describes its product as a 'reference Stereo Headphone Amplifier and Reference Line Amplifier with Relay Gain and Input Control', which should give you some idea of what's going on here, but only hints at the fact that this is actually two completely separate products packed into one relatively compact unit."
"The headphone section is powered by a power amp from THX, employing the same AAA (Achromatic Audio Amplifier) technology first used by the company in its AHB2."
"Benchmark's line amplifier uses relays for input selection, gain control and muting while four independent 256-step attenuators ... feed the the headphone ... and preamp outputs."
"As PM notes in his Lab Report, this design gives the HPA4 not only outstanding performance, but also rather impressive - to say the least - signal delivery."
"All of a track or two should do the trick, as whether with revealing headphones ... or used as a preamp, the HPA4 simply drops jaws with the sheer impact, openness and vivacity of the way it plays music."
"It was one of those real 'performer in the room' experiences and I was instantly transported back to the time I spent monitoring the recording as it was being made ..."

"Here's a brand that's aptly named - its products providing a 'benchmark' technical performance. The HPA4 is no exception with its relay-switched stepwise volume attenuator calibrated in 0.5 dB steps over a 'useable' 105 dB range."
"Distortion and noise are vanishingly low."
"The frequency response is ruler flat (+/- 0.01 dB) from 1 Hz - 100 kHz."
"The [line output] source impedance is a sensible 30 Ohms and the maximum output a huge 22 V."
"Via the headphone amp, the maximum voltage is 11.2 V and ... the maximum power output is a substantial 4.4W/25ohm and 7.7W/8ohm."
"So, not only will the HPA4 drive the toughest headphone loads but its ... insignificant -102 dBV (8uV) residual noise also ensures exceptionally quiet backgrounds when listening with the most sensitive headphones/earbuds."
"Distortion is broadly unaffected by loading."
"The source impedance is a low <0.6 Ohms up to 10 kHz, increasing to 0.78 Ohms at 20 kHz."

"The Benchmark HPA4 is one of the most transparent headphone amps I have ever heard — at any price."
"Just as impressive is the line stage, which delivers volume control that many an esoteric analog or digital preamp could only dream of."
"To say I am impressed with Benchmark HPA4 would be an understatement."
"Based on my impressions, the Benchmark HPA4 receives two Everything Audio Network Stellar Sound Awards. One for its headphone amp and one for its line stage. Folks, it is that good."

"The Benchmark HPA4 is the best sounding line amplifier I've yet heard."
"It's innovative approach to controlling system volume/SPL results in what for me is a uniquely transparent-to-source experience."
"For the first time in my audio life I can pin my ear to each speaker driver and hear absolutely no sound coming from the speakers in a quiet room with the system volume control at any position from minimum to maximum with no source material playing."
"I find that lowering the background noise paints the music on as black a canvas as possible and thus seems to bring out realistic low-level detail in recordings."
"It is also the best sounding headphone amp I've heard, both for very-insensitive, hard-to-drive phones and those sensitive enough to easily be used directly from a smart phone."
"The HPA4 truly stands apart in terms of measured and subjectively low background noise and distortion when driving either loudspeakers or headphones."

"I’m immediately struck by the way the depth presented by the current model immerses you in the recording."
"Having put the DAC3 through its paces with a wide range of tube and solid state amplifiers for The Audiophile Apartment, as the core of a high performance, yet highly compact system, the DAC3 is a charmer, indeed."
"The three-dimensionality is the best I’ve achieved on my reference system."
"This is a special digital product indeed."
"Since the introduction of the original DAC1, Benchmark has set the industry on its ear..."
"We gave the original DAC1 our first Exceptional Value award in issue 3, and the current DAC3 HGC is an equally good value, earning this award again in 2017."
- Marck Marcantonio, Tone Audio
by Benchmark Media Systems September 15, 2017
"Although similar in appearance to previous Benchmark models, with a front-panel volume control and two ¼" headphone jacks."
"The new DAC2 HGC uses four 32-bit ESS Sabre DACs, run in balanced configuration, for a significantly lower noise floor; has a new Hybrid Gain Control (HGC) for volume attenuation, which combines active analog gain control and passive low-impedance attenuators in the analog realm with a 32-bit digital DSP gain control for digital signals."
"It had a pleasantly forward sound, with smooth highs, a solid bottom end, and excellent image separation, said EL."
by Benchmark Media Systems July 18, 2017
"I am confident in saying the DAC3 has hit the Goldilocks spot in tonal balance ... it always sounded, just right."
"Benchmark was and is a pro audio brand at the forefront of the democratization of the recording industry and audiophiles became interested in the product line toward the end of the last decade."
"Despite looking very similar to the DAC1 and DAC1 HDR, and virtually identical to the DAC2 HGC, the DAC3 HGC brings a lot of ‘new’ to the table."
"There’s an intrinsic sense of honesty to the sound ... it always sounded, just right… in the Goldilocks sense."
- Alan Sircom, Hi-Fi+

"With all the headphones I had available the DAC2 headphone amp rivaled the sonics of the stand-alone iFi iCan headphone amplifier ..."
"For me the bottom line on the Benchmark DAC2 HGC is that is it not only good enough to live with long-term, it’s good enough to use for any mastering or recording projects that might come up."
"The DAC2 HGC is easy to listen through, highly revealing, and with well-recorded material astonishingly three-dimensional."
- Steven Stone, The Absolute Sound
by Benchmark Media Systems July 14, 2013
"The audio quality of the DAC2 is pretty stunning and like a lot of high quality amplifiers the first thing to jump out here was the soundstage."
"This and instrument separation gave a presentation which is hugely revealing and very enjoyable with good recordings although that comes with it an obvious double edged sword (depending on your preferences)."
"After these wow factors came the detail, now I'm not saying the detail is the 3rd best aspect, it's just that it hit me in that order. I think the best way to describe the detail is precise and edgy."
"Combine this machine with a pair of headphones that already display those traits and you have yourself a pretty impressive experience."

"Fit and finish of this component is top notch. My unit came in the black finish and it was physically perfect."
"The Benchmark DAC makes for a smooth and pleasant presentation of music, even on older material like Jimi Hendrix's Blues album (MCA). On "Hear My Train A Comin'" the guitar was lively and clear, while bass of the drums was well portrayed. "Catfish Blues" had a depth and energy that made the piece so powerful to listen to, and the emotion continued through "Voodoo Chile Blues" keeping plenty of air around the instruments making for a very open presentation."
"The Benchmark DAC1 HDR is a landmark piece. Its small size and inclusion of not only a great DAC but remote controlled preamp with analog input as well as a flexible headphone amplifier make this a great piece for a top notch system at a reasonable price."
