Overview

Benefiting from half a decade of technological innovation since the release of its acclaimed predecessor, the NAD M33 V2 integrated amplifier delivers cutting-edge improvements at every level. Enhanced digital-to-analogue and analogue-to-digital conversion, advanced signal processing, refined bass management and room correction, and an upgrade to second-generation Purifi Eigentakt Class D amplifier modules all contribute to a new reference standard in audiophile stereo amplifier design.

Conservatively rated at 200 watts per channel continuous into 8 ohms and 380 watts per channel into 4 ohms, the M23 V2 is a reference power amplifier—a masterclass in sheer output, sonic clarity, and compatibility with even the most demanding speakers. Dynamic output of 2 x 260W into 8 ohms and 2 x 520W into 4 ohms ensures the tactile punch of your music is preserved and delivered effortlessly.

Pure sound delivered by Purifi

Continuing NAD’s long tradition of identifying and implementing cutting-edge amplification technology, the M23 V2 Stereo Power Amplifier employs the newest generation of Eigentakt Class D stereo amplifier modules. Harmonic and intermodulation distortion are almost immeasurable at all frequencies and output levels. Noise is inaudible, delivering your music with the utmost clarity and transparency. Output impedance is also extremely low, ensuring iron-clad control of any loudspeaker load and consistent bass performance at any listening level. For those seeking the best in audiophile stereo amplifier performance, the M23 V2 is a compelling choice.

In a class of its own

The ideal audiophile amplifier will combine vanishingly low distortion, ultra-high damping, and rock-solid stability with any loudspeaker. While many amplifiers perform well in one or two of these areas, the NAD M23 power amplifier, featuring Purifi’s groundbreaking second-generation Eigentakt technology and NAD’s proven switch mode power supplies, excels in all of them. This design enables the M23 V2 to outperform typical Class D amplifier implementations, delivering unmatched musical performance and energy efficiency—all without the weight and heat of traditional analogue power stages. Thanks to NAD’s expert implementation, the M23 offers superior performance in power, transparency, and efficiency, making it a leading contender for the best amplifier in its class.

Designed for seamless integration and flexibility

Equipped with single-ended RCA and balanced XLR stereo amplifier auto-sensing inputs, a three-position gain-control switch, and an intelligent 12V trigger input and output, the NAD M23 V2 Stereo Power Amplifier can be seamlessly integrated into a high-performance separates system—especially when paired with the NAD M66 BluOS Streaming DAC Preamplifier. The M23 V2 can also operate in bridged mode, delivering 700W of continuous power into 8 ohms. For those building a powerhouse system, two M23 V2 amplifiers can be paired in bridge mode, with a one-second delay built into the 12V trigger output to prevent surge spikes. Listeners can also pair the M23 V2 with the NAD M33 V2 integrated amplifier in bridged mode, creating a formidable setup with 700W per channel—ideal for hi-fi streaming amplifier enthusiasts looking for power and control with BluOS streaming capabilities.

Practical elegance

With its elegant all-alloy casework, the M23 V2 Stereo Power Amplifier showcases the premium design philosophy of the NAD MASTERS Series. Rigid panels and magnetic iso-point feet provide a rock-solid foundation for the M23 V2’s multi-layer circuit boards and intricate internal layout. The result is an amplifier that is as pleasing to the eye as it is thrilling to the ears. For listeners searching for a 200W power amplifier, or a system optimized for high-resolution audio, the M23 V2 delivers a distinctive combination of sonic authority, design finesse, and future-ready technology—setting a new benchmark in NAD Hi-Fi amplifiers.
