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

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

"All I can say is Wow!"

- John Atkinson

LA4 - Receives Stereophile's Top Rating for Preamplifiers

"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

HPA4 - Receives Stereophile's Top Rating for Headphone Amplifiers

"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

AHB2 - Receives Stereophile's Top Rating for Power Amplifiers

"An extraordinary amplifier."

- John Atkinson

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

- Kalman Rubinson

"This is the best headphone amplifier that I have ever tested. In every conceivable metric, absolutely perfect."

"If you've got the money and you want something that is an engineering masterpiece, this is such a thing."

- AP Mastering

"With over 40 years as an audiophile and more than half those years as a hi-fi retailer, I feel I’ve finally put together a stereo that ticks all my sonic boxes. Those being in order of priority, dynamics, scale, tonal accuracy, fatigue free resolution and soundstage."

"For the last 25 years I’ve been fortunate to have a dedicated listening room. I use acoustic treatments from Real Traps, Vicoustic and Primeacoustic."

"My Benchmark components consist of the DAC3 B (connected to a Naim NDS streamer), LA4 line amplifier and two AHB2 power amplifiers run in bridged mono mode. All cables are Benchmark too."

"The Benchmark gear in my system has brought what I have wanted in my list of sonic priorities as listed above and then some. They have delivered way beyond what I thought could be possible in my system in my room."

"I’m delighted and stunned daily as my vast music collection comes to life on a whole new level."

- Ricky Dasler, Living Sound, Nelson New Zealand.

"What are the Latest Advancements in Mastering?"

"Geoff Pesche weighs in on how the mastering team at Abbey Road Studios achieve first-class results." - Mix with the Masters

"The biggest sonic improvement in mastering in the last 5 or 6 years is D/A and A/D converters and that's very very important - what you have at the front and the back of the chain."

"We use fairly new Benchmark converters front and back."

"Abbey Road like a uniformity between the rooms so all of the rooms have the same A/D and D/A conversion."

- Geoff Pesche, Mastering Engineer, Abbey Road Studios

"A Damn Good, No-Frills Digital Converter"

"Benchmark Media Systems’ no-nonsense approach to all things audio is rare today."

"Uniformly Good"

"This is a DAC that’s uniformly good at everything. It resolves well, has good imaging properties."

"It makes a balanced, honest sound that allows you to sit and listen to music for hours. That is what makes Benchmark’s products consistently popular with audio engineers. You don’t want ‘bright’ if you sit at a mixing desk 10 hours a day. "

"Leave No Trace"

"It also has the latest version of Benchmark’s jitter attenuation system (UltraLock3) and doubles down on the digital demon with its multi-mode asynchronous USB system."

"Benchmark also uses the distortion compensation facilities built into the ESS chip to reduce second and third order distortion."

"The net result is a DAC that delivers lower distortion, lower noise, less passband ripple, faster signal switching and locking onto signals and a more linear frequency response."

"The Benchmark Media Systems DAC3 B is very much in the ‘leave no trace’ school of good audio."

- Alan Sircom, hi-fi+

2024 Nominees

• 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."

"Benchmark Media Systems made its reputation in both pro audio and audiophile circles by designing gear with extraordinarily low noise and distortion, and selling it at reasonable prices."

"What Makes the Benchmark LA4 Preamp So Special?"

"A high-quality volume control is much of what makes a superior preamp shine, and the Benchmark’s volume control is outstanding. The Benchmark LA4 uses a bank of precision resistors switched by gold-contact relays to set volume in 256 steps of 0.5 decibels each."

"If accurate reproduction is your wish, you won’t find a preamp with meaningfully better objective performance than the Benchmark LA4, especially one made in the United States at anything near the LA4’s price."

"Very few preamps at any price reach the LA4’s level of objective performance."

"On the subjective end of things, the Benchmark LA4 preamp puts the lie to the old audiophile myth that neutrality means clinical, cold, or sterile sound. Instead, here neutrality means musical, involving sound, with precise, stable imaging, a sense of space (if one is on the recording), and exceptionally truthful timbres."

- Mike Prager, FutureAudiophile.com

"For years, the audio world acknowledged one main contender (at least at sub-five-figure pricing) for the quietest, cleanest, most neutral power amplifier around. That was the Benchmark AHB2, whose specifications are still, for all practical purposes, unsurpassed, even by today’s excellent Class-D amps."

"10 years after its release, the Benchmark Media Systems AHB2 stereo power amp is still a standard-bearer in clean, neutral sound in the audiophile world."

"I greatly enjoyed having a pair of AHB2s in my system – their purity, neutrality, and seemingly unlimited power provided a clear window on the music and a lot of joy."

"I especially appreciated the AHB2’s smooth, well-integrated treble, free of splashiness or grain, and its natural reproduction of the human voice."

- Mike Prager, Future Audiophile

"The AHB2 bridgeable stereo amplifier ... was the topic of a recent discussion between American electrostatic panel speaker manufacturer Sound Lab’s president, Dr. Roger West, and me."

"In our discussion, he related his highly positive experience in driving even his largest, $55k Majestic 945 panels with the $7,000 pair of Benchmark Media AHB2 monoblocks, along with the $3,050 LA4 Preamplifier and factory XLR cables."

"Dr. West described the AHB2 as a class AB design using “feed-forward distortion reduction [thus removing] any possibility of pushing the margin of safety of a standard feedback loop, used in most amplifiers, into an unstable oscillatory mode.”"

"He further shared with me that “this is of most concern on powerful musical transients. The distortion of the amplifier in the balanced mode is astonishingly low even at just below the clipping level of 380 watts.”"

"The prospect of the AHB2’s specified distortion level of 0.00015% or lower when at full volume is comical at first glance, but upon actual audition the impact of the achievement is very audible from medium-high listening levels and upward."

"It was unlike any other sub-$20,000 amplifier I have auditioned."

"My audition of the Benchmark Media AHB2 amplifiers underscores the reason Dr. West is so taken by it, and confirms the design is best described as a watershed moment in the high-end audio industry."

- Constantine Soo, Dagogo

"Benchmark is a stalwart brand in pro audio, but has carved out a very respectable niche in the audiophile world with their diminutive but powerful components."

"The audiophile world sometimes looks to the professional audio world for enlightenment, especially on the digital side of things, and Benchmark Media is one of the companies that we put high on a pedestal."

"They are hardcore digital engineers freezing their asses off in upstate New York as they come up with some pretty innovative ways to get your varied digital sources sounding as much like the master tape as possible. Thank you for your service, gentlemen."

"If you really want to hear what your music sounds like in today’s streaming-driven world, this might just be the DAC that you need to test out."

- Jerry Del Colliano, Future Audiophile

"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."

"The Sound of Silence"

"Benchmark Audio is an engineering focused company with a deep heritage in the recording studio world."

"The HPA4 is a Headphone Amplifier and Preamp that incorporates the THX-888(AAA) achromatic audio amplifier circuit that was first introduced to the world in the Benchmark AHB2 amplifier."

"To this day the AHB2 remains the lowest distortion and highest SNR amplifier on the market."

"The Direct Opposite of Typical Tube-Based Technology"

"From a listening stance it is the cleanest and most accurate delivery of sound you are likely to get with any Hi-Fi component."

"This is the direct opposite of the typical sound of tube-based technology that is awash in second harmonic distortion and noise."

Power

"The HPA4 …offers 6 watts into 16 ohm and a whopping 11.5 Vrms into 300 Ohm headphones."

"You will not be running out of power with this device."

Listening

I used the track "Slink" from the brand-new Artemis album on Blue Note."

"It is a very dynamic driving track and the Artemis ensemble makes the most of it. The HPA4 and revealed all the sonic details of this track."

"I give the HPA4 my highest recommendation."

- Chris, Forum Administrator - DC Hi-Fi Group

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."
