NAD Electronics Master Series M23 Stereo Power Amplifier

Building on NAD’s long tradition of identifying and developing cutting-edge amplification technology, the M23 HybridDigital Stereo Power Amplifier features Purifi Audio’s Eigentakt™ design, a once-in-a-decade innovation that virtually eliminates harmonic and intermodulation distortion. Noise is inaudible, for a completely black background and exquisite micro-detail. Conservatively rated at 2x200W continuous into 8 ohms and 2x380W into 4 ohms, the M23 can deliver live performance levels through any loudspeaker. With its unique combination of features, performance, and value, the M23 represents the new benchmark for the stereo power amplifier.

A Newer, Purer Sound

Continuing NAD’s long tradition of identifying and developing cutting-edge amplification technology, the M23 Stereo Power Amplifier employs Eigentakt™ class-D amplifier modules manufactured by NAD under license from Purifi. Harmonic and IM distortion is almost immeasurable at all frequencies and output levels. Noise is inaudible, for a black background and outstanding micro-detail. Output impedance is extremely low, which translates to iron-clad control of any loudspeaker load.

Amazingly powerful and transparent, the M23 can deliver 2x260W of dynamic power into 8 ohms and 2x520W into 4 ohms.

In a Class of Its Own

The ideal amplifier will combine vanishingly low distortion, ultra-high damping factor, and rock-solid stability with any loudspeaker. There are many amplifiers that perform well in one or two of these areas but fall short in others. Purifi’s ground-breaking Eigentakt™ technology and NAD’s proven switch-mode power supplies enable the M23 to excel in all these areas – without the excess weight and cost of the old-fashioned linear power supplies and class-AB output stages used with traditional amplifiers. In all these areas, Eigentakt™ outperforms previous class-D implementations by a significant margin.

Flexibility

Equipped with single-ended RCA and balanced XLR auto-sensing inputs, three-position gain-control switch, and 12V trigger input, the NAD Masters M23 Stereo Power Amplifier can easily be integrated into a high-performance separates system. The M23 can operate in bridged mode, delivering 700W continuous power into 8 ohms. Two M23 amplifiers operating in bridged mode can be paired together, or listeners can combine the M23 with NAD’s award-winning Masters M33 BluOS Streaming Amplifier, both operating in bridged mode, to configure a staggeringly powerful system with 700Wpc continuous output.

Practical Elegance

With its elegant all-alloy casework, the M23 Stereo Power Amplifier has the quality of construction for which NAD’s Masters Series is renowned. Rigid panels and magnetic iso-point feet provide a rock-solid foundation for the M23’s multi-layer circuit boards and intricate internal construction. The result is an amplifier that is as pleasing to the eye as it is thrilling to the ears. Offering a unique combination of features, performance, and value, the M23 represents the new benchmark for the stereo power amplifier.
