NAD’s New M23 Hybrid Digital Stereo Power Amplifier: Purifi Eigentakt!

NAD’s New Master Series M23 Hybrid Digital Stereo Power Amplifier employs the company’s Purifi Eigentakt amplifier technology for claimed clean, clear power. Lots of power.

Fromm the press release:

The Masters M23 Hybrid Digital stereo power amplifier features Eigentakt™ amplifier technology, manufactured by NAD under license from Purifi. This new technology nearly eliminates harmonic and intermodulation distortion and allows for an even, wide, and load-invariant frequency response.

In common with the previous generations of NAD Hybrid Digital technology but unlike most Class D amplifier designs, the M23 offers a minimum of 200W per channel with amazing reserves of dynamic power at lower impedances. It is capable of beyond 260W dynamic power per channel even into 8 ohms, and beyond 520W into 4 ohms. It can effortlessly power any loudspeaker to live performance levels with amazing efficiency and low power consumption.

Effortless power is never a bad thing.

When run in Bridge Mode, a pair of M23s deliver a whopping 700 mono Watts into 8 Ohms.
I appreciate the new NAD’s clean, simple lines.

The M23 can also mate with the matching NAD M33 BluOS Streaming Amplifier (pictured on the right) to create a 2x 700W system.

The NAD M23 Hybrid Digital Stereo Power Amplifier will be available this month with an MSRP of $3499.
