For sale: Grace Design m920 – Reference-Grade DAC / Headphone Amplifier / Monitoring Preamp (Audiophile / Mastering Level)

The Grace Design m920 is widely regarded as one of the most transparent and precise monitoring and conversion systems ever built. In my setup, it has been used not only as a monitoring controller but also as a dedicated mastering DAC, serving as the final conversion stage for critical mastering decisions. It delivers an exceptionally uncolored, ultra-linear sound signature that reveals every detail in a recording without hype or coloration.

If you’re looking for a true reference chain component that disappears sonically and simply lets you hear deeper into your music, this is it.

This unit is in excellent condition and has been used with care in a professional, smoke-free studio environment.
