NAD's proven hybrid digital circuitry and the proprietary "Eigentakt" technology from Danish digital amplifier pioneer Purifi were introduced almost two years ago with the integrated streaming amplifier M33 (reviewed by us here). According to the manufacturer, the technology is characterized by extremely low intermodulation, a particularly low distortion factor over the entire frequency response and bandwidth, minimal inherent noise, as well as insensitivity to varying speaker loads. The low output impedance leads to a very high damping factor, which is expressed in an absolutely clean and controlled bass reproduction.
This amplifier technology is now also used in the new NAD M23 stereo power amplifier, featuring a continuous power stated at 2x 200 watts into 8 or 2 x 380 watts into 4 ohms, with which it is said to be able to drive even power-hungry speakers with ease. If even higher power reserves are required, it can be operated in a bridge circuit as a mono power amplifier. The manufacturer recommends using the NAD M23 as a powerful partner for any high-quality stereo preamp or other hi-fi components that have a level-adjustable stereo preamp output.
The M23 carries balanced XLR inputs together with gold-plated RCA jacks. In addition, the M23 offers three-stage adjustable input sensitivity as well as automatic power-on when an audio input signal is present. Its elaborate enclosure is made of aluminum. In Germany, the NAD M23 power amplifier is available immediately from authorized retailers at the MSRP of around €3,500.
