M3

About the M3

The NAD Masters Series M3 is a high‑performance dual‑mono stereo integrated amplifier. Each channel has its own power supply with twin custom NAD “Holmgren” toroidal transformers and separate unregulated and discrete regulated stages, minimizing crosstalk and improving channel separation. Rated at 180 watts per channel into either 8 or 4 ohms from 20 Hz to 20 kHz with no more than 0.004% THD (both channels driven), it offers wideband frequency response, high damping factor, and very low noise. The M3 includes seven line‑level inputs (six RCA and one balanced XLR), two preamp outputs with selectable bi‑amp/low‑pass filtering (40, 60, 80, 100 Hz), speaker A/B switching, and a Zone 2/record output with independent source selection. A precision electronic volume control and balance in 0.5 dB steps, defeatable bass/treble tone controls, and NAD’s PowerDrive circuitry round out a feature set aimed at combining pre/power performance in a single chassis.
