NAD M23 Master Series Stereo Power Amplifier

A NEW PINNACLE OF POWER, PERFORMANCE, AND VALUE

The NAD Masters M23 HybridDigital Stereo Power Amplifier features Eigentakt™
amplifier technology, a once-in-a-decade innovation that virtually eliminates harmonic and
intermodulation distortion; and delivers wide, flat frequency response regardless of the
loudspeaker load. The result is transparent, detailed sound with pinpoint stereo imaging,
at all listening levels and with all types of program material – even during complex musical
passages. Conservatively rated at 2x200W continuous into 8 ohms and 2x380W into 4 ohms,
the M23 can deliver live performance levels through any loudspeaker.

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 are 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 awardwinning 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.
