M23 V2 Stereo Power Amplifier

With any loudspeaker load, the ideal amplifier will achieve vanishingly low distortion, ultra-high damping factor, and rock-solid stability. The M23 employs Eigentakt class-D amplifier modules manufactured by NAD Electronics under license from Denmark's Purifi Audio. Purifi's load-invariant design provides a wide, flat frequency response with noise, harmonic distortion, and IM distortion virtually unmeasurable at all frequencies and output levels. It outperforms previous class-D implementations by a significant margin, delivering transparent, detailed sound with an expansive soundstage and holographic imaging at all listening levels and with all types of program material—even during complex musical passages. Additionally, extremely low output impedance and correspondingly high damping factor are achieved for iron-clas control of the loudspeaker output.

The Eigentakt design is paired with NAD's very own high-performance 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. Tanks to Purifi's highly efficient Eigentakt design and NAD's proven switch mode power supplies, the M23 excels in all three areas—without the excess weight and cost of the old-fashioned linear power supplies and class-AB output stages used with traditional high-end amplifiers.
