Why This Is Here

Grace Design has been in professional audio since the 1990s. The M900 brings that engineering to a desktop unit, and the DAC stage is the best we stock at any price point — not just good for the price, objectively good.

Who It's For

Serious listeners who want their source chain to be above reproach. Anyone who has built a serious headphone collection and wants the DAC stage to match.

I worked at Grace Design and helped design headphone amps like this. Professional grade, transparent, powerful enough for anything, digital and analog inputs. This is what I'd use if I were setting up a serious headphone monitoring system. It's expensive, yes, but you're getting reference-grade amplification. Most people don't need this. But if you're doing critical work on headphones? This is what professional means.
