The DAC1 HDR incorporates several of Benchmark's proprietary designs: the AdvancedUSB computer audio interface, the DAC1 digital-to-analog converter, and the HPA2 headphone amplifier. It builds on Benchmark's DAC1 PRE with the addition of a unique remote control solution and motorized volume potentiometer.

John Atkinson praises the DAC1 USB as a "superb-sounding device. And the fact that it has an excellent-sounding headphone output with two choices of maximum gain makes it a bargain. Very highly recommended."

"I'd say that if you're working on computer audio files, are doing a lot of work ripping PCM music, or have a media server, the DAC1 USB would be a valuable addition to your system. "

Benchmark is honored to receive Pro Audio Review's Reviewer's Pick Award for the PRE420.
