NAD M33 V2

BluOS® Streaming DAC Amplifier

The NAD M33 V2 BluOS® Streaming DAC Amplifier builds on the performance of its predecessor with a more advanced approach to signal processing, conversion, and amplification. With second-generation Eigentakt™ amplification, an upgraded ESS DAC and ADC architecture, and timing-focused technologies from MQA Labs, the M33 V2 is engineered to reveal more of the nuance, texture, and expression within each recording, allowing music to sound more natural and engaging. By developing each stage of the audio path as part of a unified system, the M33 V2 reduces noise and timing errors while maintaining consistency across both digital and analogue sources, resulting in a clearer, more stable presentation that brings greater focus to the listening experience.

Includes Dirac Live® Limited Bandwidth licence and calibration microphone for room correction up to 500Hz

PRECISION AMPLIFICATION WITH MUSICAL CONTROL

Second-generation Eigentakt™ amplification delivers high power with exceptionally low distortion, allowing the M33 V2 to maintain control across a wide range of loudspeakers. Beyond output, it preserves the subtle shifts in dynamics and phrasing that give music its shape and expression. The result is a presentation that feels composed, responsive, and fully resolved, even during complex passages.

ENGINEERED AROUND HOW WE HEAR

The M33 V2 reflects a deeper understanding of how sound is perceived. Research into human hearing shows sensitivity to extremely small timing differences, and the system is designed to preserve that accuracy throughout playback. Technologies such as FOQUS and QRONO from MQA Labs reduce timing errors during conversion, helping maintain the natural alignment and flow of musical elements so that recordings sound more cohesive and lifelike.

BUILT TO EVOLVE WITH YOUR SYSTEM

The M33 V2 features NAD’s Modular Design Construction platform, with two MDC slots that allow the system to adapt as new technologies emerge. This approach extends the lifespan of the product while maintaining performance over time. As systems grow or change, the M33 V2 remains a stable foundation, designed to integrate seamlessly with new sources and configurations.

CONTROLLED, CONNECTED, AND EASY TO LIVE WITH

The M33 V2 combines high-performance audio with flexible connectivity and intuitive control. BluOS enables high-resolution multi-room streaming through the BluOS Controller App, with support for a wide range of music services and formats. Additional options such as AirPlay 2, aptX HD Bluetooth, Roon, and HDMI eARC allow the system to integrate easily into everyday listening, while the 7-inch touchscreen display provides clear, direct access to playback and system settings.

CALIBRATED FOR YOUR ROOM

Dirac Live Room Correction, with support for optional Bass Control, calibrates the M33 V2 to your listening environment. By addressing room-induced effects, it improves low-frequency accuracy, clarity, and tonal balance. The result is a more stable and natural presentation, where instruments and voices retain their position and character across different listening conditions.
