DAC3 B - "Neutral and Transparent"

"In the areas of tonal neutrality and transparency, the B sounds like every other Benchmark I’ve heard, which is to say neutral and transparent. But the DAC3 also has new conversion processing, which is said to make for a 3.5dB increase in headroom above 0dBFS, in turn preventing the DSP intersampling overloads."

"This increase in headroom ... is said to result in subtly improved sound."

LA4 - "Line Amplifier"

"Benchmark prefers to call the LA4 a line amplifier (which may be the more correct term because that is what preamplifiers in fact do: amplify the signal) and offers it in two versions: linestage only, and the identical linestage with an onboard headphone amplifier, called the HPA4."

AHB2 - "A Genuinely Innovative Design"

"Before properly introducing the preamp, however, it is worth the while to recall that the AHB2 amplifier is a genuinely innovative design, even, if you will, revelatory, and it set new standards in having by a wide margin the lowest noise and distortion and the widest bandwidth of any amplifier on the market then or now."

DAC3 B, LA4, AHB2 - "The Presentation is Uncanny in its Purity"

"There’s a complete absence of any sort of artifacts or noise; on very clean recordings, the presentation is uncanny in its purity."

- Paul Seydor, The Absolute Sound

AHB2 - "Legendary Performance Award 2020"

"My first taste of this remarkable new amplifier came earlier this year in April at Chicago's AXPONA where I discovered it driving a newly redesigned Studio Electric Pasadena loudspeaker, also bearing the Benchmark trademark. Now called the SMS1, the Pasadena's crossover had been reworked by Benchmark, upgraded with very low tolerance components, and the new look, more in line with the look of the rest of the Benchmark product line up, had been adopted."

"The subsequent sound in this room was one of the most musically engaging I encountered at this year's event, a remarkable result considering its modest overall system price of just over $7000, sans source."

DAC3 HGC - "A+ Recommended Digital Processor"

The DAC3 HGC received Stereophile's top "A+" rating.

Jim Austin wrote, "The DAC3 was all about depths, in several respects . . . I heard deeper into the music."

The concise conclusion to John Atkinson's Measurements sidebar: "All I can say is 'Wow!'"

In a Follow-Up, Jim Austin wrote of using the Benchmark processor with the same company's AHB2 power amp—a combination of high source output voltage and modest amplifier gain that he describes as "optimal for minimizing noise and distortion"—and reported hearing "richer and more interesting" reproduction of very subtle details.

- Stereophile Magazine

"Class A+" is Stereophile's highest award for Digital Processors

LA4 - "Class A - Recommended Preamplifier"

The LA4 received Stereophile's top "Class A" rating in the preamplifier category.

"Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered."

- John Atkinson, Stereophile

"The LA4 is probably the most transparent and revealing audio component I've ever used. It does not seem to leave any fingerprints on the sound."

- Kalman Rubinson, Stereophile

"Class A" is Stereophile's highest award for preamplifiers.

AHB2 - "A-Rated Power Amplifier"

The AHB2 received Stereophile's top "A" rating for power amplifiers.

"Much more apparent low-level detail in already-familiar recordings"

"Sounded more 'right' than any of [the other amps on hand]."

- Kalman Rubinson, Stereophile

"An extraordinary amplifier"

- John Atkinson, Stereophile

"In measuring the AHB2 and attempting to confirm its specified (very) high signal/noise ratio, JA observed nonlinearities in his testing equipment that "haven't affected the measured performance of other amplifiers I've tested, but they were detectable with the AHB2's very low intrinsic distortion and noise." His conclusion: "an extraordinary amplifier.""

"Class A" is Stereophile's highest award for power amplifiers.

LA4 - TAS Golden Ear Award

"I am so floored by its performance that a Golden Ear is a forgone conclusion."

"The LA4 comes closer to measured and measurable perfection than any audio product in any category I've ever reviewed."

"It has lower distortion and noise than any electronic component known to me, and its transparency is without equal in my experience, with no sonic signature that I can identify."

"Its dynamic range is likewise at the highest state of the art. An amazing 256-step volume control maintains 0.5 dB/step resolution and flawless channel-tracking at any setting throughout its range."

"This is my new reference standard for a linestage."

- Paul Seydor, The Absolute Sound

AHB2 - "I Purchased the Review Sample"

"The Benchmark AHB2 is a very fine sounding, easy to live with, zero-maintenance power amplifier that has enough power for most systems. If more power is needed, two amplifiers configured for mono can provide it."

"The decision to purchase the review sample and make the Benchmark AHB2 a new, long term reference took over a month of listening and comparisons."

"The outstanding musicality of the Benchmark AHB2 takes some time to convince the listener of its wholly musical presentation. This subtle excellence assures long term satisfaction."

- Jerry Seigel, 10 Audio

AHB2 - "Perfect 10" Award

DAC3 B - 10 DACS, 10 Judges, 1 Winner

Alpha-Audio.net tested 10 DACs side-by-side. Only one received the "Alpha-Audio Approved" award. That DAC was the Benchmark DAC3.

DAC3 B - "Alpha-Audio Approved!"

"Are you looking for the best DAC (d/a converter) in the price range from 1500 euro to 2500 euro? That’s great! Because we’ve put ten beauties side by side. And we tested it live on camera for you."

"It was incredibly instructive to put so many converters side by side. We clearly hear differences - and the viewers could as well."

"One of the models we all agreed on is the benchmark DAC3. This is a delicious musical product. Virtually no coloring, nice stereo image and plenty of inputs."

"Our final round of the best products from the finest brands of the last 20 years, covering products made from early 1999 to 2019."

"Benchmark is perhaps best known for its range of DACs, but the new HPA4 shows just what the brand can do with a take-no-prisoners headphone amplifier design."

"A real game-changer!"

LA4 - "EAN Top Product of 2019" - All Categories

"Thanks to the special, discrete analog circuit/relay attenuator, this may be the most transparent line-stage preamplifier in the audiophile world."

"If you got a great-sounding source, the LA4 presents the audio in its original state — with gain or attenuation to the amplifier."

"I have never heard such low-level detail from a pre."

"The better the DAC, the better you hear it through a quality amp and speakers. It is quiet as a top-notch DAC, with S/N exceeding -135 dB and, feature-wise, it comes with unbalanced/balanced I/O and a really slick user interface."

"I use the four-input LA4 for audiophile A/B testing of DACs, monitoring my Hi-Res home recording/editing/mastering projects, as well as just listening how good my vast collection of 24 bit and DSD music sounds through an accurate amp and speakers."

"A steal!"

- John Gatski, Everything Audio Network

AHB2 - Driving Selah Cali4 Speakers - "Room of Distinction"

"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!"

HPA4 - TAS 2019 Product of the Year

"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."

- Tom Martin, The Absolute Sound

HPA4 - "As Good as it Gets"

"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."

- AV Tech Media Awards 2018/2019

Stereophile's editors chose 10 products to receive their top award, the "2018 Product of the Year - Editor's Choice Award". Two Benchmark products made this exclusive list - the AHB2 power amplifier and the DAC3 HGC D/A converter.

AHB2 - 2018 Editors' Choice Award

"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

DAC3 HGC - 2018 Editors' Choice Award

"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

AHB2 - Top 3 Finalist - "Amplification Component of the Year"

The competition in the amplification category was very tight. There was a two-way tie for first place between two amplifiers that cost $30,000 a pair and $13,500 a pair. 

The Benchmark AHB2 was just two points behind the leaders when the Stereophile reviewers cast their final votes. In all, there were 13 amplifiers that made Stereophile's select list of finalists. The Benchmark AHB2 was the least expensive amplifier on the list, yet it received top scores from the reviewers. The list included amplifiers with stratospheric prices. Six amplifiers were priced between $25,000 and $118,000 a pair!

At Benchmark we believe that a great audio system shouldn't set you back by the cost of a sports car.

HPA4 - "Top Product of 2018" - All Categories

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"

- John Gatski, Everything Audio Network

DAC3 DX - "Best High-End DAC"

"The Benchmark DAC3 DX DAC is designed for recording and mastering studios, but it is a great product for consumer use as well. Its clean, low distortion analog output and flexible setup controls will bring the studio to your home audio system."

- John E. Johnson, Jr., Editor-in-Chief

Tie for First Place, 16x Price Difference

DAC3 HGC - Top Two Finalist - "Digital Component of the Year"

"This contest produced another tie, and yet another contrast between two wildly different philosophies—economical, if not technical. As Jim Austin pointed out in his initial review, the DAC3 HGC D/A processor from Benchmark Media Systems—a company known for making pro-audio as well as domestic-audio gear—sells for less than the price of certain high-end interconnects. The dCS Vivaldi D/A processor sells for 16 times the Benchmark's price, and in our pages was first reviewed, by Michael Fremer, as part of a $114,996 dCS digital front end."

"Both DACs impressed their respective reviewers with magnificent sound—and in his measurements for both, John Atkinson offered the same one-word conclusion: "Wow!""

LA4 - "Best of RMAF 2018"

"RMAF 2018 was really good, with significant numbers of attendees, and more new-product introductions than I remembered ever seeing there."

"Led by engineer John Siau and based in Syracuse, New York, Benchmark Media Systems has built a sterling reputation for making compact, well-engineered, moderately priced electronics that challenge the state of the art, both on the test bench and in the listening room."

"What I took notice of were the specifications: total harmonic distortion of less than 0.00006%, and a signal/noise ratio exceeding 135dB from 20Hz to 20kHz."

"If those claims are true, and there’s no reason to believe they aren’t -- Benchmark gear has always performed as specified on the test bench -- the LA4 should be about as transparent-sounding a line-stage as you can find at any price." 

- Doug Schneider, SoundStage! Hi-Fi

HPA4 - Hi-Fi News "Outstanding Product"

"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 ..."
