AHB2 Review - Paul Rigby, The Audiophile Man
AHB2 - "The Perfect Heart to any Hi-Fi"
"Starting with Dakota Staton’s album ‘Round Midnight from the original Capitol release, issued in 1960, I connected the Benchmark to my Quad 57 electrostatics."
"Staton’s vocal delivery was calm, even and smooth without any edginess to her delivery and certainly without any brightness or blooming during crescendos. Her even-handed vocal delivery was very pleasant indeed."
"As for the instruments backing Staton, I was impressed by the tonal accuracy of the introductory strings and the clarinet. Both, backed by the similarly impressive low noise nature of the soundstage, had room to express themselves that enhanced the richness of their performance."
"Everything was in order and everything was in its place. Part of the reason for this was the low noise so, right from the off, the music was much more focused than many other components."
"Bass was never one dimensional but had a layered personality of its own."

Caution:
In his review, Paul Rigby mentions driving Quad ESL-57 electrostatic speakers using the AHB2 in bridged-mono mode. Potentially, this mode will provide too much output to the ESL-57 speaker and this may cause damage. The ESL-57s are rated for a maximum input voltage of 33V. The AHB2 can deliver 40V in stereo mode and 80V in mono mode. Mono mode can severely overdrive the ESL-57 speakers and may cause permanent damage to the electrostatic panels. The AHB2 should be used in stereo mode when driving ESL-57 speakers. Apparently the AHB2 gain switch was configured for a lower gain than Paul's other amplifier. This led him to believe that the AHB2 needed to run in bridged-mono mode when driving his ESL-57 speakers. The correct action would have been to turn up the preamplifier and/or adjust the gain switch on the back of the AHB2.

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."

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."

DAC3 - Award Nominee - Best Digital Audiophile Product of 2024 (Cost No Object)
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."
