The NAD Masters M23 HybridDigital stereo power amplifier integrates Eigentakt™ amplifier technology, a breakthrough in decades of innovation that virtually eliminates harmonic and intermodular distortion. It thus offers a wide frequency response, with no ups and downs, regardless of the speaker load.
The result is a crisp, detailed sound with an accurate stereo image at all listening levels and with all types of melodies, even during the most complex and demanding musical passages.
In keeping with NAD's long tradition of identifying and developing cutting-edge amplifier technology, the M23 stereo stage features Eigentakt™ Class D amplifier modules manufactured by NAD under licence from Purifi.
Harmonic distortion and IM is virtually impossible to measure at all frequencies and output levels due to its marginality. Noise is inaudible, allowing a clean background that allows all details to stand out. Output impedance is extremely low, resulting in firm control of the speaker load.
With amazing power and transparency, the M23 can deliver dynamic power of 2 x 260W at 8 ohm and 2 x 520W at 4 ohm.
Purifi's Eigentakt™ technology has changed the game, giving NAD devices a proven power switching mode that makes them excel in all three of these areas. All without the weight and price increase common in older power amplifiers with Class AB output stages used in traditional amplifiers. Eigentakt™ outperforms in all of the above ways, and by a wide margin, the improvements in the Class D system.
Equipped with single-ended RCA and balanced XLR inputs with signal auto-sensing, three-position gain control and 12V trigger input, the NAD M23 power amplifier integrates easily into any high-performance sound system.
The NAD M23 can operate in bridge mode, delivering 700W of continuous power at 8ohm. A pair of M23s in bridge mode can be linked together with the award-winning NAD M33 BluOS Streaming Amplifier for an impressive 700W of continuous power.
