Benchmark's DAC3 HGC—the last three letters designate this as the audiophile version, with a headphone amp and two analog inputs—supports files up to 24/192 and DSD64, the latter as DoP (via USB). Bearing in mind the manufacturer's suggestion that there should be no audible difference between their DAC1 and DAC3, Jim Austin wrote, "In fact, I found the sounds of the two DACs quite different. The DAC1 was brighter . . . the DAC3 was all about depths, in several respects . . . I heard deeper into the music." The concise conclusion to John Atkinson's Measurements sidebar: "All I can say is 'Wow!'"
'Class A+' is Stereophile's highest classification for digital processors. Stereophile defines Class A and the digital processor Class A+ as follows:
"Best attainable sound for a component of its kind, almost without practical considerations; "the least musical compromise." A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing. With Super Audio CD, DVD-Audio, and Hi-Rez PCM and DSD files now available, we have created a new Class, A+, for the best performance in those digital categories."
In a Follow-Up, Jim Austin wrote of using the Benchmark processor with the same company's AHB2power 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.

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!"
