M23 V2
Stereo power amplifier rated at 200 W per channel into 8 ohms and 380 W into 4 ohms, with a bridged mono mode of 700 W. It suits hi-fi systems that need a high-current amplifier with balanced or single-ended inputs and multi-amp trigger control.
- 200 W/ch into 8 ohms, 380 W/ch into 4 ohms (stereo)
- Bridged mono mode: more than 700 W into 8 ohms
- Second-generation Purifi Eigentakt with NAD HybridDigital
- Auto-sensing balanced XLR and single-ended RCA inputs
- Three-position gain control and 12V trigger with delay
- All-alloy chassis, 9.7 kg net weight

The M23 V2 is a two-channel power amplifier built around the second generation of Purifi Eigentakt amplification modules combined with NAD's HybridDigital design. It is rated at more than 200 W into 8 ohms and more than 380 W into 4 ohms in stereo, and can be bridged into a mono amplifier delivering more than 700 W into 8 ohms. Damping factor is above 800 and peak output current exceeds 25 A into 1 ohm.
Inputs are auto-sensing between balanced XLR and single-ended RCA, with a three-position gain control for matching to preamplifiers such as the NAD M66 or M33 V2. A 12V trigger with a delay supports systems with several amplifiers. Power comes from a switch-mode supply, and the electronics sit in a rigid all-alloy chassis laid out to limit interference.
The chassis measures 435 x 133 x 381 mm and weighs 9.7 kg. Frequency response is within ±0.06 dB from 20 Hz to 20 kHz in stereo mode, and signal-to-noise ratio is above 101.7 dB.
