The implementation of the Purifi Eigentakt amplifier technology in NAD’s new Masters M23 hybrid digital stereo power amplifier aims to deliver audiophile performance and value.
First introduced in the M33 BluOS streaming amplifier, NAD claims the Purifi Eigentakt amplifier platform virtually eliminates harmonic and intermodulation distortion and noise while its load-invariant frequency response can drive even the most demanding of loudspeakers to their highest performance. The result is a wide, flat frequency response, detailed transparent sound and accurate imaging regardless of the loudspeaker load.
Part of the NAD Masters Series, the M23 Stereo Power Amplifier employs Eigentakt class-D amplifier modules manufactured by NAD under license from Purifi and in common with the previous generations of NAD Hybrid Digital technology, it can offer a minimum of 200W per channel at 8 ohms (and 2x 380W into 4 ohms). Moreover, it is capable of 260W dynamic power per channel into 8 ohms and 520W into 4 ohms, effectively powering loudspeakers to live performance levels.
Combining the Eigentakt technology with NAD’s switch-mode power supplies, the M23 moves away from old fashioned, power-hungry linear power supplies and Class A/B output stages to enable low distortion, ultra-high damping and rock-solid stability with any loudspeaker. NAD reckons Eigentakt outperforms previous Class-D implementations by a significant margin.
The M23 can operate in bridged mode, delivering 700W continuous power into 8 ohms and is thus an ideal addition to expand the power of an M33 BluOS streaming amplifier or is an easy upgrade to power any high-performance separates system.
Furthermore, integration into a separates system is facilitated by a single-ended RCA, balanced XLR auto-sensing inputs, a three-position gain-control switch, 12V trigger input and auto sensing.
The M23 features an elegant yet practical all alloy casework with rigid panels with magnetic iso-point feet to provide a solid foundation for the multi-layer circuit boards and internal construction.
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.”
The NAD Masters M23 Stereo Power Amplifier is available in January 2022 priced at £2999 (€3499 / US$3499 / CDN$4599 MSRP).
