DAC3 and LA4 Review - Paul Seydor, The Absolute Sound
DAC3 B - "Neutral and Transparent"
"In the areas of tonal neutrality and transparency, the DAC3 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."
Conclusions
"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."
"The bandwidth of the LA4 goes out to beyond 500kHz at the top end, while its low-end -3dB point is 0.01Hz."
"Bass through the LA4 driving the ABH2 is outstandingly clean and clear, with superlative definition, articulation, and registration of timbre."
"I find myself in the same conundrum as when I reviewed the ABH2. Once more I have literally nothing to write about. There’s a complete absence of any sort of artifacts or noise; on very clean recordings, the presentation is uncanny in its purity."
"You will notice I haven’t said a word about detail. This is deliberate. It is a non-issue. With noise and distortion at the sub-subterranean levels of the LA4, the AHB2, and the DAC3 B, what could possibly remain that would eat, mask, or fail to retrieve even the lowest-levels of recorded information?"

The LA4 Receives Top Awards from TAS
In September of 2020 the Benchmark LA4 received a 2020 Golden Ear Award.
In January 2021, the LA4 received a 2020 Product of the Year Award in the Solid-State Preamplifier category.

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."
