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 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.
The DAC3 HGC was one of three products to receive Stereophile's top award for 2018, the "Overall Component of the Year".
The DAC3 HGC was also nominated as a finalist for Stereophile's "2018 Headphone Product of the Year". Ultimately, this award went to the Audeze LCDi4 in-ear headphones.
"I love, I love, I love my Benchmark AHB2 power amps!"

Theo uses a pair of AHB2 power amps in bridged mono (480 W into 6 Ohms) to drive a pair of Revel Ultima Salon2 loudspeakers ($20,000/pair). This is his reference amplifier-speaker combination.
