"The Benchmark DAC3 offers extremely low levels of harmonic distortion from all its outputs. Intermodulation distortion was similarly vanishingly low."
"The Benchmark DAC3 featured extraordinarily low levels of analog noise at its outputs."
"No power-supply–related spuriae can be seen, and the random noise floor lies below –160 dBFS!"
"With its very low noise floor and correspondingly very high resolution, the DAC3’s reproduction of an undithered 16-bit tone at exactly -90.31 dBFS was perfect."
"When the DAC3 decoded dithered 16-bit and 24-bit data representing a 1 kHz tone at -60 dBFS, the increase in bit depth dropped the noise floor by more than 30 dB, indicating that the Benchmark’s resolution is at least 21 bits."
"This as good as a DAC can currently get!"
"Channel separation via the digital inputs was superb, at 124dB in both directions at 1kHz, and was still almost 110dB at 20kHz."
"The analog inputs offered a very wide frequency response that was not affected by reducing the load impedance from 100k ohms to 600 ohms or by varying the volume-control settings.The channels were superbly matched, both dropping by only 2dB at 200kHz."
"As with its predecessor, the DAC2 HGC, which Erick Lichte reviewed for Stereophile in February 2014, Benchmark’s DAC3 HGC offers state-of-the-art measured performance."
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.'"
"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."
