L'avis de Noir & Blanc
Connect to the emotion of live performance through detailed sound, with both amazing control and transparency.
This is the M22. 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, vivid 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 good sound. You just have to hear it to feel it.
The M22 is using the latest nCore™ amplifier technology licensed from Hypex to provide a nearly ideal amplifier with distortion below measurement,
ultra-high damping factor, and unconditional stability with any speaker. Tight, detailed sound with amazing control and transparency gets the best performance available. With nCore, Hypex has refined their UcD concept to new levels of perfection by improving the modulator for more accurate feedback subtraction and PWM generation.
The all-discrete driver and output stage have also been improved for lower open-loop THD as well as lower idling losses, normally conflicting requirements with conventional IC driver circuitry.
An added control loop incorporating an integrator with adaptive clipping enables 20dB more feedback to be used across the audio band because of its extremely low-phase shift resulting in a dramatic reduction in distortion across the audio band.
This is added to UcD’s already amazing characteristics of load invariance and high current capability, common characteristics of great-sounding amplifiers.
