• Benchmark Media DAC3 B DAC, $1895
• Bricasti M3 DAC, $6000
• Bricasti M19 CD-SACD Player, $10,000
• T+A DAC 200, $7620
• Weiss Engineering Helios DAC, $21,995

"There was some debate about whether anybody can hear the differences above a good Chi-Fi DAC like the Topping D90. Unless you are missing most of your high-frequency hearing, you can hear where a high-end DAC makes a difference."

The Bricasti M3 is a great example of that performance in a $6,000 DAC."

"The Benchmark DAC3 B is an audiophile DAC, with pro audio roots, that punches way above its weight."

"I began with the DAC3 HGC and AHB2 powering the glorious Morel Avyra 633 three-way floorstanders."

"This pairing created a full-bodied sound which brought the recording to life."

"Notable from the off was the bass from the DAC3 HGC and AHB2."

"Wow! It was deep, tight and conveyed a real feeling that the electronics were in charge of the transducers."

"Involuntary foot-tapping confirmed the timing ability and the overall presentation was spot-on, the Benchmark electronics created a fluent sound across a vivid soundstage; performers evident both tonally and spatially in an easy-to-believe presentation that brought the performance close."

"The Benchmark’s ability to retrieve deep-down detail and display it so well across the soundstage, with accurate positioning and convincing layering, made for a glorious re-creation of the recordings."

"To my mind the AHB2 is an amplifier with no obvious characteristics of its own: the level of transparency is sublime."

"Above all, the improved transient response performance stood out in a presentation that was not only lively but incredibly fast and revealing. The attack and decay displayed was awesome and not something I expect at this price point."

"The Benchmark DAC3 HGC and AHB2 are cracking products, sonically superior to a lot that’s available and well priced."

"They are superbly designed and built to an extremely high standard."

- Trevor Butler, the-ear.net

AHB2 - Receives Stereophile's Highest "A" Rating for Power Amplifiers

"Benchmark's AHB2 makes use of THX Corporation's Achromatic Audio Amplifier (AAA) technology, in which a low-power feed-forward amplifier drives a low-bias class-AB output section."

- Stereophile, 2023

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

"A tonal balance that sounded more 'right' than any of [the other amps on hand]." - Kalman Rubinson

"An extraordinary amplifier." - John Atkinson

LA4 - Receives Stereophile's Highest "Class A" Rating for Preamplifiers

"Benchmark's usual approach to design is to out-spec the competition, and so it is here. Like other Benchmark equipment he has tested, the affordable LA4 challenged the resolution of John Atkinson's test instruments, with 'superb' channel separation, 'extremely low noise, and virtually no power-supply-related spuriae.'"

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

"In his listening room, Kalman Rubinson compared the LA4 to a cable—and couldn't hear any difference. He concludes, '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.'"

- Stereophile, 2023

DAC3 HGC, DAC3 B - Receive Stereophile's Highest "Class A+" Rating

"The DAC3 B is a stripped- down, lower-priced version of the DAC3 HGC, which omits the headphone amplifier, balanced and unbalanced analog inputs, volume, mute, and polarity controls." - Stereophile

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

"All I can say is Wow!"

- John Atkinson

"In a Follow-Up, JCA 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

HPA4 - Receives Stereophile's "Class A" Rating for Headphone Amplifiers

"The HPA4 adds a THX888 amplification stage to Benchmark's LA4 line preamplifier  to allow it to drive even low-impedance headphones with aplomb."

"It keeps the LA4's balanced and single-ended preamplifier outputs and adds a headphone output on a 4-pin XLR jack and a single-ended headphone output on a 1/4" jack."

- Stereophile, 2023

"The HPA4 showed each instrument in dramatic bas-relief. It accomplished this by presenting cleaner, better-articulated bass and manufacturing a sharper midrange focus than I had experienced previously with either my solid state reference, the Pass Labs HPA-1, or the tubed Linear Tube Audio Z10e." - Herb Reichert

"The LA4 preamplifier was the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I had encountered at that time. . . . To those virtues, the HPA4 adds equally superb balanced and single-ended headphone outputs." - John Atkinson

DAC3 B - Receives Stereophile's Highest "Class A+" Rating

"I never auditioned the DAC3 HGC in my own system, so when I got an opportunity to borrow a sample of the DAC3 B, I eagerly agreed."

"I had been using MBL's network-connected N31 CD player/DAC ($18,680 with Roon Ready module) before installing the DAC3 B."

"The MBL offers an excellent sense of drive and low-frequency impact, but when I replaced it with the Benchmark, both these aspects of the music seemed enhanced."

"Whether it was an orchestral bass drum or a kickdrum, electric bass guitar or acoustic double bass, the MoFi speakers seemed to acquire more low-frequency weight without losing definition."

- John Atkinson

AHB2 - Stereo Times "Most Wanted" Award

"Merriam-Webster defines a benchmark as "something that serves as a standard by which others may be measured or judged." This is what the AHB2s has become for me."

"A pair of AHB2s are now part of my dedicated summertime amplification for my Sound Lab 545PX loudspeakers."

- Don Shaulis, The Stereo Times

AHB2 - "I Purchased Two Units With My Hard-Earned Money"

"The highest compliment I can give to AHB2 is that I purchased not one, but two units with my hard-earned money. These weren’t loaner units and this wasn’t a sponsored review and you can draw your own conclusions."

"The AHB2 might look small and lightweight, but thanks to its clever engineering and power supply implementation, this little fellow could still deliver 190 Watts in 4 Ohms and 100 Watts in 8 Ohms, while maintaining an undetectable noise floor and distortion."

"For the craziest folks out there, you can even bridge two pieces together for ~580 Watts in 4 Ohms and 380W in 8 ohms."

- Sandu Vitalie, SoundNews.net

LA4 - "Best Volume Control"

"By far, without question this is the best volume control I have ever encountered."

"I must single out for special mention the volume control. While the whole unit is completely relay controlled, with a total of forty “precision relays switching high-precision metal-film resistors,” each channel has its own gain control with 256 steps in 0.5dB increments."

"Suffice it to say that, as with every Benchmark product I’ve used or reviewed, everything works smoothly, precisely, flawlessly."

- Paul Seydor, The Absolute Sound

HPA4 - "Best High-End Stereo Preamplifier"

"The Benchmark Media Systems HPA4 preamplifier is an exceptionally transparent and well-designed audio device."

"I found it to be an extremely neutral reference point that allowed me to hear more of what a connected speaker or headphone was actually doing and, in turn, how much my existing electronics were adding to the sound that I was hearing in my reviews."

- Carlo Lo Raso, Co-Editor, Secrets of Home Theater and High Fidelity

HPA4 - Ear 5-Star Rating

"Benchmark’s HPA4 is the first item of audio kit I have encountered that peels apart the ying and the yang of audio to expose the fault line between those of us for whom measurements are all that matters… and those of us that approach audio from a more emotional, less scientific direction. But in another sense it might also bridge the divide."

HPA4 Driving the Audeze LCD-5

"It had been the arrival of Audeze’s latest flagship planar headphone the LCD-5 that had prompted me to ask if I might borrow an HPA4."

"With the LCD-5 being a statement 14 Ohm/90db design, I felt I owed it to Audeze and myself to try driving the headphone with an amplifier whose specs suggested that it could easily cope with the requirement for current."

"The LCD-5 and HPA4 made an impressive partnership."

"On more energetic material, such as Marcus Miller’s M2 album from 2001, and the aptly named track Power, the LCD-5 showed that the HPA4 couples deep reserves of low-end grunt with a good level of dynamic expression. At loud but not silly volumes, the boom and snap of Miller’s slap bass technique had timing and tonal qualities that to my ears – alas, I do not have Miller’s talent but I do play bass – sounded uncommonly real through the LCD-5 headphone."

"I’d encourage anyone in the market for a high-end headphone amplifier to audition an HPA4."

"It is a device that achieves stellar measurements, yet sounds excellent too; evidence that the science-based approach can deliver high musicality."

"The HPA4 can drive pretty much anything, its resolution is truly remarkable, and you will likely hear your music with an acuity as never before."

-Kevin Fiske, the-ear.net

AHB2 - "A-Rated Power Amplifier"

The "A" rating is the highest honor awarded in the Power Amplifier category.

"Benchmark's AHB2 makes use of THX Corporation's Achromatic Audio Amplifier (AAA) technology, in which a low-power feed-forward amplifier drives a low-bias class-AB output section."

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

"A tonal balance that sounded more 'right' than any of [the other amps on hand]." - Kalman Rubinson

"An extraordinary amplifier." - John Atkinson

HPA4 - "Class A Recommended" Headphone Amplifier

"With the hard-to-drive HiFiMan Susvara headphones, the HPA4 showed each instrument in dramatic bas-relief. It accomplished this by presenting cleaner, better-articulated bass and manufacturing a sharper midrange focus than I had experienced previously with either my solid state reference, the Pass Labs HPA-1, or the tubed Linear Tube Audio Z10e.”

- Herb Reichert

"The LA4 preamplifier was the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I had encountered at that time ... to those virtues, the HPA4 adds equally superb balanced and single-ended headphone outputs."

- John Atkinson

LA4 - "Class A Recommended Preamplifier"

"Class A" is the highest level awarded in the "Two Channel Preamplifier" category.

"Like other Benchmark equipment he has tested, the affordable LA4 challenged the resolution of JA's test instruments, with "superb" channel separation, "extremely low noise, and virtually no power-supply-related spuriae.""

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

"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

DAC3 HGC - "A+ Rated Digital Processor"

"A+" is the highest level awarded in the "Digital Processor" category.

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

"Benchmark's DAC3 HGC offers state-of-the-art measured performance. All I can say is 'Wow!'" - John Atkinson

AHB2 - "Thumbs Firmly Aloft"

Stereonet Applause Award - Benchmark AHB2

"I can't think of many amps with dual hi-fi and pro functionality. Maybe Bryston and the odd ATC, but there aren't a lot. However, to this shortlist, we can add Benchmark."

"Two things strike you upon first seeing it – it's surprisingly compact, and it also has the sort of features that make it more at home in a studio than a listening room lounge space."

"You can bridge the AHB2 to make it a monoblock, or bi-wire it to a single speaker; there are only balanced connections incoming, as well as a choice of gain to match the speaker. You get normal speaker binding posts plus a pair of Neutrik's SpeakOn connectors on the output side."

"Thumbs firmly aloft then for this compact, versatile, thoughtfully designed, well-built stereo power amplifier."

- Rafael Todes, Stereonet.com

DAC3 B, HPA4, AHB2 - "Purchased Them for My Reference System - Nuff Said!"

"The Benchmark 'stack' ... saw use with a wide variety of loudspeakers and other electronic equipment."

"Having the Benchmark stack here for an extended period also made me re-evaluate a few things about how and what I use to review equipment."

"I dare say that they produced as clean and noise-free a stereo playback chain as I have ever come across."

"Benchmark Media Systems is a well-regarded brand that is known for its high-quality DACs and ADCs that also find their way into professional studios."

AHB2 Power Amplifier

"In 2014 they introduced the AHB2 power amplifier, using patented THX AAA amplifier technology, that brought previously unheard of low levels of distortion, and high SNR capability."

LA4 and HPA4

"Last year Benchmark released the LA4 preamplifier and the HPA4 headphone amplifier. Both components use an ultra-precision relay-based volume control and feature vanishingly low levels of distortion."

DAC3 B

"The DAC3 B is an alternate version of the DAC3 DX that ... simply does away with the included volume control and headphone jacks which makes it ideal to use with the HPA4 or LA4."

"The Benchmark DAC3 B ... is a finely executed example of a modern ESS-based digital to analog converter."

The Benchmark 'Stack'

"The Benchmark Media Systems HPA4 preamplifier, AHB2 power amplifier, and DAC3 B are, individually, exceptionally transparent and well-designed audio devices."

"When used as a system the resulting synergy was even more revealing."

"I liked them so much that I purchased them for my reference system. Nuff said!"

- Carlo Lo Raso, Secrets of Home Theater and High Fidelity

LA4 - Absolute Sound Product of the Year

"Suffice it to say that, as with every Benchmark product I’ve used or reviewed, everything works smoothly, precisely, flawlessly."

"I must single out for special mention the volume control. While the whole unit is completely relay controlled, with a total of forty “precision relays switching high-precision metal-film resistors,” each channel has its own gain control with 256 steps in 0.5dB increments."

"By far, without question this is the best volume control I have ever encountered."

"The LA4 has been widely tested with results that tell the same story as those from the AHB2 power amplifier, i.e., the measurements merely confirm the manufacturer’s claims except in those instances where the limits of the test gear are reached before this or that specification can be precisely verified, almost every tester reporting that the unit beats, often handily, any other ever tested in its product category, regardless of price."

- Paul Seydor, The Absolute Sound

DAC3, LA4, AHB2 - "Matched My Idea of Reference Sound"

"Benchmark is an audio brand that started in Texas in 1983. The company then moved to the founder's hometown of Syracuse, New York, and all products are still designed, assembled, and tested at the Syracuse factory. This benchmark has officially arrived in Japan."

"I had the opportunity to listen to all the products of the American audio brand Benchmark Media Systems, and I was very impressed by how well they matched my idea of ​​reference sound."

"The biggest appeal that all the five models we tested have in common is their sound quality, which you can absolutely trust as a reference."

LA4/AHB2 System - "HiVi 2020 Grand Prize" - Amplifier Category

"A compact amplifier with outstanding high performance that is compatible with AV systems."
