Overview
Connect to the emotion of live performance through detailed sound, with both amazing control and transparency. While it is easy to find amplifiers that can excel in one or two areas, the M22 is an amplifier that truly does everything well. Wide open-loop bandwidth, extremely low-phase shift, almost non-existent noise, and high current capability all add up to one incredible performance. Wielding NAD’s PowerDrive™ circuit topology, the M22 delivers unbelievable power to any loudspeaker. Distortion and noise become functionally nonexistent and nearly unmeasureable thanks to the M22’s switch mode design, resulting in a clear, amazing sound. Possessing harmonic and intermodulation distortion independent of load, as well as low output impedance uniformly at all audible frequencies, the M22 is a powerhouse unit built to break down barriers to audiophile-grade sound.
