BLUOS STREAMING DAC-PREAMPLIFIER

The NAD M66 BluOS Streaming DAC-Preamplifier is designed as the starting point of a high-performance two-channel system, bringing together streaming, digital-to-analogue conversion, analogue control, and room optimisation into a single, cohesive platform. With a flagship ESS Sabre DAC, precision analogue volume control, and advanced room correction, the M66 preserves the integrity of every source, allowing music to retain its tone, detail, and natural flow. Whether streaming, playing vinyl, or connecting external components, the M66 delivers a clear and composed presentation that reveals more of the performance, making it a natural partner for power amplifiers such as the NAD M23 V2.

Includes Dirac Live® Full Bandwidth licence and calibration microphone for full-range room correction

COMPLETE CONTROL FROM SOURCE TO OUTPUT

COMPLETE CONTROL FROM SOURCE TO OUTPUT

The M66 is designed to maintain signal integrity across the entire audio path. A flagship ESS Sabre ES9038PRO DAC handles digital conversion with low noise and wide dynamic range, while NAD’s implementation preserves tonal accuracy and low-level detail. The analogue volume control maintains precise channel balance across all listening levels, ensuring that dynamics and musical expression remain intact from input to output.
ENGINEERED FOR HOW MUSIC IS HEARD

ENGINEERED FOR HOW MUSIC IS HEARD

The M66 incorporates technologies that address how sound is perceived, not just how it is measured. With innovations such as Dynamic Digital Headroom and advanced ADC and DAC stages, it reduces distortion caused by digital clipping and timing inconsistencies. The result is a more natural and fluid presentation, where transients are clean, textures are preserved, and music retains its sense of timing and flow.
SEAMLESS ACCESS TO YOUR MUSIC

SEAMLESS ACCESS TO YOUR MUSIC

BluOS transforms the M66 into a high-resolution streaming hub, providing access to music services, internet radio, and personal libraries through the BluOS Controller App. Music can be played in a single room or shared across multiple zones with consistent performance. Navigation is responsive and intuitive, allowing you to move through your collection easily while keeping the focus on listening rather than managing technology.
CALIBRATED FOR YOUR ROOM

CALIBRATED FOR YOUR ROOM

Dirac Live Room Correction, with support for Dirac Live Bass Control, adapts the M66 to your listening environment. By addressing room-induced effects, it improves low-frequency accuracy, tonal balance, and spatial clarity. The result is a more natural presentation, where instruments and voices are better defined and remain consistent across different listening positions.
BUILT FOR SYSTEM INTEGRATION

BUILT FOR SYSTEM INTEGRATION

The M66 supports a wide range of analogue and digital sources, from vinyl playback to high-resolution streaming and TV audio via HDMI eARC. Balanced and unbalanced connections allow seamless pairing with a variety of power amplifiers, while a dedicated headphone amplifier supports detailed and controlled private listening. Compatibility with leading control systems ensures the M66 integrates naturally into both simple and advanced environments.
