AHB2 Review - Peter Davey, Positive Feedback
AHB2 - "It's phenomenal! Gobs of power, detail, finesse and control."
"Benchmark has been around for a long time. In fact, they are one of the early Audiophile pioneers of USB DACs ... I had always thought of them as more of a digital conversion company, and not an amplifier company—until the AHB2 came about."
"A PF colleague of mine (Steven Lefkowicz) said... Dude, you HAVE to try the Benchmark in your system (which at the time was going through a gamut of speaker changes as part of a myriad of reviews being done for PF) to which I replied, wow, they have an amp?"
"I was immediately taken aback with the level of detail given to this unit. Just one glance at the back plate will tell you that this is a well-engineered piece of equipment. Fully Balanced = Check. Speakon Outputs = Check. Bridging Support = Check. Input Sensitivity Adjustment = Check. 12v Trigger support = Check."
"The front panel is rather minimalist; a few LEDs to indicate the health of the amp and a power button. There is even a way to program the amp to turn on if it senses power so one can integrate it into a secondary power system if you wanted to (which then turns the power button into a mute circuit). Or, just leave it on all of the time. Even at LOUD levels, it does not get hot."
"I'm currently running it at a 4 Ohm stereo load, and the 190 Watts is going a long way! To be honest I haven't heard the amp clip yet, and I listen to music at cathartic levels sometimes (sorry, neighbors!). I believe these measurements to be on the conservative side."
"So, how does it sound, after all of that? Well, this thing is no slouch. It's phenomenal! Gobs of power, detail, finesse and control. I have thrown so much music at this tiny little amp, that I just can't seem to beat it to submission. It just takes it in and gives it right back. The damping factor is really at play here."
"For the price, you just can't beat it. If you have been looking for an all-in-one chassis stereo Class A/B amplifier that is reliable, energy efficient, and one of the best designs on the market, this is the ticket (it even comes in Black!). Most other offerings are at LEAST twice as expensive, and I can speak from experience that they don't sound half as good as this one. If I had the means, I'd keep this one as a perfect Swiss-army knife and never let it go. Hell, if you're feeling insecure about power, you can get two of them for cheaper than most Class A/B monoblocks out there, and have twice the power. Think no more, do it!"

Benchmark System Review - Ricky Dasler, Living Sound, New Zealand
"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."

Benchmark Converters at Abbey Road - Geoff Pesche
"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
DAC3 Review - Alan Sircom, hi-fi+
"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."
