Benchmark DAC1 USB As A Headphone Amplifier Impressively engineered, easy to set-up and operate... and dead quiet. Review by A. Colin Flood

enjoythemusic.com

The Benchmark DAC1 USB is praised for its impressive engineering and user-friendly setup, delivering a clean, neutral sound that audiophiles appreciate. However, its neutrality sometimes translates to a lack of emotional engagement, leaving some rock tracks feeling a bit lifeless. While it excels in clarity and bass definition, it lacks the warmth and punch found in some tube amplifiers. Despite its high price, the DAC1 USB offers value as a solid-state DAC/amplifier, though its sonic invisibility might not appeal to those seeking more dynamic coloration. Overall, it's a reliable piece for purists but may not suit everyone.
