Behind the Design of the NAD Masters M23 Power Amplifier

M23 Amplifier 3/4 view


NAD’s Masters M23 stereo power amplifier features Purifi Audio’s ground-breaking Eigentakt™ technology, a once-in-a-decade innovation that virtually eliminates noise and distortion. The M23 can deliver 2×200W of continuous power into 8 ohms, and 2×380W into 4 ohms. Quite simply, the Masters M23 is the most advanced power amplifier NAD has ever offered. Here are some key characteristics of its design.

Pure Sound

The M23 is the latest example of NAD’s 50-year history of implementing cutting-edge amplifier technology. Employing Eigentakt™ class-D amplifier modules manufactured by NAD under license from Denmark’s Purifi Audio, the M23 delivers wide, flat frequency response, even into challenging loudspeaker loads. Harmonic and IM distortion are almost unmeasurable at all frequencies and output levels, exhibiting transparent sound, expansive soundstaging and pinpoint imaging – even during complex musical passages. Thanks to its extremely low noise floor, the M23 can deliver exquisite micro-detail. Another characteristic of the M23’s Eigentakt™ design is its very low output impedance, which gives the amplifier iron-clad control over loudspeaker output.

Power To Spare

NAD complements the highly effcient Eigentakt™ design with our own innovative switch-mode power supply, which can provide huge reserves of current on demand. As a result, the M23 can deliver 2×260W of peak power into 8 ohms and 2×520W into 4 ohms, for effortless reproduction of musical transients. It achieves this without the excess weight and cost of old-fashioned class-AB amplifiers with linear power supplies.

A Perfect Pairing

Two M23 amplifiers operating in bridged mode can be paired together to configure a powerful system with 700W per channel of continuous power. Alternatively, the M23 can be combined with NAD’s award-winning Masters M33 BluOS streaming DAC-amplifier, also operating in bridged mode, for a system with 700W per channel continuous output.

Timeless Beauty

Featuring elegant all-alloy casework, the M23 power amplifier has the same 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 construction. The result is an amplifier that is as pleasing to the eye as it is thrilling to the ears.
