description

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.

Robust stereo power

The NAD Masters Series M23 is a superior option for setting up a high-performance two-channel sound system. It delivers 200 watts x 2 at 8 ohms and an impressive 700 watts into a single channel in bridged mode. It's 4-ohm-stable, so it can handle even demanding, power-hungry speakers.

Innovative Class D amplifier technology

This amp pushes Class D amplification performance to new limits thanks to HybridDigital Purifi Eigentakt™ technology. It helps the amp maintain even frequency response into lower impedance loads and minimizes the occurrence of digital clipping. This advanced design offers robust power output and accurate sound with minimal distortion, without the excess weight and cost associated with more traditional linear power supplies and Class AB output stages.

Convenient connections

The M23 offers individual unbalanced RCA and balanced XLR inputs for each channel, for making solid connections to a quality NAD preamp. There's 12-volt trigger input for remote turn-on, so your whole system can power up with a single click.
