The Masters M66 BluOS Streaming DAC-Preamplifier is a revolutionary hi-fi component that combines an audiophile-grade DAC with a high-resolution multi-room music streamer. Featuring Dirac Live Room Correction and Dirac Live Bass Control, its elegant design and vibrant 7″ touchscreen exudes quality and class. Pair it with NAD’s M23 power amplifier for a stunning system that excels technologically, sonically, and visually.
Not only is the Masters M66 BluOS streaming DAC-preamplifier the most advanced preamplifier NAD has ever offered, it represents an entirely new class of hi-fi separate components. In addition to a plethora of inputs, including MM/MC phono and HDMI eARC, the M66 incorporates an audiophile-grade DAC and a high-resolution multi-room music streamer.
Along with the full-bandwidth version of Dirac Live Room Correction, the M66 features Dirac Live Bass Control, allowing independent control of each connected subwoofer, for smooth, consistent response throughout your listening room. The combination of Dirac Live Room Correction and Dirac Live Bass Control enables the M66 to deliver more accurate in-room performance than any two-channel component ever offered.
With its elegant aluminium casework, super-smooth digital volume control, and vibrant 7″ touchscreen, the M66 exudes class and quality. Visually, sonically, and technologically, it’s an ideal match to NAD’s award-winning Masters M23 power amplifier. Of course, the Masters M66 BluOS Streaming DAC-Preamplifier can be paired with any high-performance amplifier.

What is Dirac Live?
Dirac Live is an advanced room correction and sound optimisation technology that dramatically improves your audio experience. By analysing how sound behaves in your space, it automatically adjusts your speakers to eliminate distortion, correct timing issues, and balance the overall sound.
When integrated with an AVR, Dirac Live measures the acoustic characteristics of your space using a calibrated microphone, analysing how sound interacts with the room. It then adjusts the speaker’s output to ensure that the sound is balanced and true-to-source, regardless of the room’s shape, size, or materials. This process includes aligning the timing and phase of the speakers to provide a cohesive, immersive sound field—something that would be impossible to achieve with just speaker placement alone.
Contrary to basic EQ systems that mainly flatten the frequency response, Dirac Live corrects both the frequency and impulse response. This means it not only addresses tonal balance but also ensures that transient sounds (like a clap or a drum hit) are reproduced cleanly without smearing or delay. With its capability to adjust for phase issues between speaker drivers, Dirac Live creates a more accurate and immersive audio experience that feels more natural and more true to the recording . By using Dirac Live, you’re essentially enhancing the performance of your sound system by making the sound more realistic and detailed, even in challenging spaces.
