The HybridDigital NAD Masters M23 stereo power amplifier integrates Eigentakt™ amplification technology, an advance that only occurs in decades of innovation that virtually eliminates harmonic and intermodular distortion. In this way it offers a wide frequency response, without ups and downs, regardless of the speaker load.
The result is detailed, clear sound with a precise stereo image at all listening levels and with all types of melodies, even during the most complex and demanding musical passages.
Continuing NAD's long tradition of identifying and developing cutting-edge amplification technology, the M23 stereo stage features Eigentakt™ Class D amplification modules manufactured by NAD under license from Purifi.
Harmonic distortion and IM are practically impossible to measure at all frequencies and output levels given their marginality. The noise is inaudible, allowing a clean background that allows all the details to stand out. The output impedance is extremely low, which results 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, offering NAD devices a proven power switch mode that makes them outstanding in all three of those areas. All this without the increase in weight and price common in older power amplifiers with Class AB output stages used in traditional amplifiers. Eigentakt™ surpasses in all the previous ways, and by a large margin, the improvements in the class D system.
Equipped with single-ended RCA and balanced
The NAD M23 can operate in bridge mode, offering 700W of continuous power at 8ohm. A pair of M23s in bridge mode can be linked together and the award-winning NAD M33 BluOS Streaming Amplifier, for an impressive 700W of continuous power.
