nad m3 specs reviewNAD M3 amplifier review: is a Dual mono integrated amplifier with 2-channels of 180-watts of pure power. The NAD M3 amp offers internal switching for two pairs of speakers and tone controls as well as a second Zone 2 output with independent commands and even its own remote control.
Performance features include a precision volume attenuator with 0.5dB steps and a range of 87.5db, a remote balance control with 0.5dB steps, and a Mode control which allows stereo, left only, right only and mono settings.

Tone controls offer bass and treble adjustments as well as a “spectral tilt” option that is highly effective at correcting the tonal balance of many recordings by simultaneously increasing the bass and decreasing the treble (and vice versa) to create a warmer or cooler balance. There are also a second set of preamp outputs and a switchable high-pass filter for the internal amplifier.

The M3 is NAD’s concept of the ideal musical companion, capable of transporting the listener to that place where the music simply exists in its own perfect space. For this task we have pushed classical analog circuit design to unprecedented levels of performance. The total lack of audible noise and distortion is the result of some very sophisticated analog engineering, and rather surprisingly, the use of digital control.
