NAD Launches New M23 Hybrid Digital Stereo Power Amplifier

NAD Masters Series power amplifier features Purifi Eigentakt amplifier technology to deliver audiophile performance with exceptional value.

NAD Electronics argues it takes value and performance to a whole new level with the M23 Hybrid Digital stereo power amplifier (£2999 / €3499 / US$3499 / CDN$4599 MSRP). The machine builds on the Purifi Eigentakt amplification technology first introduced in the M33 BluOS Streaming Amplifier – according to the maker, a once-in-a-decade amplifier innovation that will define the pinnacle of power and performance in the category for years to come. Continuing NAD’s tradition in identifying and developing cutting-edge amplification technology, Eigentakt looks to eliminate armonic and intermodulation distortion and noise while its load-invariant frequency response can drive even the most demanding of loudspeakers to their highest performance.

According to Cas Oostvogel, NAD’s Product Manager, “The sonic character of the M23 is reinforced in the story told by the numbers. 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.”

Powerful Eigentakt Amplifier Technology

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 some Class D amplifier designs, the M23 offers a minimum of 200W per channel with significant 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 has been designed to power any loudspeaker to live performance levels with efficiency and low power consumption. 

The M23 in bridge mode is a strong addition to expand the power of an M33 BluOS Streaming Amplifier to create a 2 x 700W system or is an easy upgrade to power any high-performance separates system.     

Thanks to the advanced Purifi Eigentakt amplifier technology, all this power comes at a lot less cost than traditional technology while delivering improved performance, says the maker.

A Diverse Performer

NAD says the M23 HybridDigital stereo power amplifier featuring the Eigentakt amplification technology provides nearly unmeasurable distortion, ultra-high damping factor, and unconditional stability with any speaker.

Designed to leave old fashioned and power-hungry linear power supplies and Class A/B output stages behind, the M23 features proven switch mode power supplies and Class D output stages that are very linear over a wide bandwidth and provide consistent performance into all speaker loads. With tight, detailed sound, strong control, and transparency, the M23 is a stereo power amplifier that truly does break down barriers to audiophile-grade sound. 

Flexibility is another strength of the M23 with its RCA and XLR balanced inputs, bridge mode, three selectable gain levels, 12v trigger and auto sensing.

The M23 features all alloy casework that is elegant yet practical. Rigid panels with magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction. The M23 employs a completely modern and fresh take on the traditional stereo amplifier, with a combination of features, performance and value for money not found elsewhere, concludes NAD.
