NAD Masters M23 Stereo Power Amplifier
Pure Power
The M23 employs Eigentakt™ class-D amplifier modules manufactured by NAD under license from Denmark’s Purifi Audio. Purifi’s load-invariant design provides wide, flat frequency response, even into challenging loudspeaker loads. Noise, harmonic distortion, and IM distortion are virtually unmeasurable at all frequencies and output levels. Another benefit of the Eigentakt™ design is extremely low output impedance and correspondingly high damping factor, for iron-clad control of the loudspeaker output. NAD combines the Eigentakt™ design with our own sophisticated switched-mode power supply, which can provide additional reserves of current when needed. Amazingly powerful and transparent, the M23 can deliver 2x260W of peak power into 8 ohms and 2x520W into 4 ohms.
