NAD M23: But unlike most Class D amplifier

The Masters NAD M23 Hybrid Digital Stereo Power Amplifier features Eigentakt™ amplifier technology manufactured by NAD under license from Purifi. This new technology virtually eliminates harmonic and intermodulation distortion and provides a flat, wide, and load-independent frequency response.


Like previous generations of NAD’s hybrid digital technology, but unlike most Class D amplifier designs, the NAD M23 delivers a minimum of 200 watts per channel with amazing dynamic power reserves at lower impedances. It is capable of delivering dynamic power of over 260W per channel even into 8 ohms and over 520W into 4 ohms. It can effortlessly power any loudspeaker with amazing efficiency and low power consumption.


The NAD M23 in bridged mode is the ideal complement to expand the power of the NAD M33 BluOS streaming amplifier to create a 2 x 700W system or is an easy upgrade to power any high-performance audio system. It’s easy to find amplifiers that can excel in one or two areas. The NAD M23 Hybrid Digital Stereo Power Amplifier with Eigentakt amplification technology delivers virtually unmeasurable distortion, ultra-high damping factor and unconditional stability with any speaker.

Leaving behind old-fashioned and power-hungry linear power supplies and Class A/B output stages, the NAD M23 features proven switch-mode power supplies and Class D output stages that are highly linear across a wide bandwidth and provide consistent performance under any speaker load. With clear, detailed sound, stunning control and transparency, the NAD M23 is a stereo power amplifier that truly breaks down barriers to audiophile-grade sound.


Flexibility is another strong point of the NAD M23, with its balanced RCA and XLR inputs, bridged mode, three selectable gain levels, 12V trigger, and auto-sensing.

Rigid panels with iso-point magnetic supports provide a strong foundation for multi-layer PCBs and complex internal designs. The NAD M23 takes a thoroughly modern and fresh take on the traditional stereo amplifier, with a combination of features, performance and value for money not found anywhere else.
