(January 20, 2022) NAD's all-new M23 Hybrid Digital stereo power amplifier is the company's latest model to feature Purifi Eigentakt amplification. Heralded as a cutting-edge technology that delivers high levels of power at a lower cost, Eigentakt nearly eliminates harmonic and intermodulation distortion and noise while its load-invariant frequency response can confidently drive demanding loudspeakers.
The M23 is a true stereo system anchor, delivering the traditional basics with RCA and XLR balanced inputs, a bridge mode, three selectable gain levels, a 12v trigger, and auto-sensing. Its heart, however, is anything but traditional, combining proven switch mode power supplies with Class D outputs stages that are linear over a wide bandwidth. The result, says NAD, is a "tight, detailed sound" laced with control and transparency across a wide variety of speakers.
The amp's factory specified power numbers look strong, beginning with a minimum of 200 Watts per channel (2x200W into 8 ohms; 2x380W into 4 ohms) and expanding to 260 Watts of dynamic power per channel (8 ohms) and beyond 520 Watts (4 ohms). Bridge mode pushes overall power numbers even further, creating a 2 x 700 Watt system.
“The sonic character of the M23 is reinforced in the story told by the numbers," explains Cas Oostvogel, NAD’s Product Manager. "This is an amazingly powerful and transparent amplifier bringing new levels of refinement and dynamics at any level and sets a new benchmark for performance and value in its category.”
Design-wise, the M23's all-alloy casework is attractive, complete with an eyecatching topside venting area, and its rigid panels and magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction.
The M23 Hybrid Digital stereo power amplifier is priced at $3499 (CDN $4599) and is expected to hit store shelves this month.
