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.
