NAD M23 Stereo Power Amplifier
3999,00 €
Building on NAD’s long tradition of identifying and developing cutting-edge amplification technology, the M23 HybridDigital Stereo Power Amplifier features Purifi Audio’s Eigentakt design, a once-in-a-decade innovation that virtually eliminates harmonic and intermodulation distortion. Noise is inaudible, for a completely black background and exquisite micro-detail. With its unique combination of features, performance, and value, the M23 represents the new benchmark for the stereo power amplifier.
Pure Power
The M23 employs Eigentakt™ class-D amplifier modules manufactured by NAD under license from Denmark’s Purifi Audio. Purifi’s load-invariant design provides wide, flat frequency response, even into challenging loudspeaker loads. Noise, harmonic distortion, and IM distortion are virtually unmeasurable at all frequencies and output levels. Another benefit of the Eigentakt™ design is extremely low output impedance and correspondingly high damping factor, for iron-clad control of the loudspeaker output. NAD combines the Eigentakt™ design with our own sophisticated switched-mode power supply, which can provide additional reserves of current when needed. Amazingly powerful and transparent, the M23 can deliver 2x260W of peak power into 8 ohms and 2x520W into 4 ohms.
Uncompromised Performance
The ideal amplifier will achieve vanishingly low distortion, ultra-high damping factor, and rock-solid stability with any loudspeaker loud. There are many amplifiers that perform well in one or two of these areas, but fall short in others. Thanks to Purifi’s highly efficient Eigentakt™ design and NAD’s proven switch-mode power supplies, the M23 excels in all three areas – without the excess weight and cost of the old-fashioned linear power supplies and class-AB output stages used with traditional amplifiers. Eigentakt™ outperforms previous class-D implementations by a significant margin, delivering transparent, detailed sound with expansive soundstaging and holographic imaging, at all listening levels and with all types of program material – even during complex musical passages.
Flexible and Powerful
Equipped with single-ended RCA and balanced XLR auto-sensing inputs, three-position gain-control switch, and 12V trigger input, the NAD Masters M23 HybridDgital Stereo Power Amplifier can easily be integrated into a high-performance separates system. Two M23 amplifiers operating in bridged mode can be paired together, each delivering 700W of continuous power into 8 ohms. The M23 amplifier can also be paired with NAD’s award-winning Masters M33 BluOS Streaming Amplifier. With the two Eigentakt™ amplifiers operating in bridged mode, the M33/M23 combination will deliver a staggeringly powerful 700Wpc continuous output.
Elegant and Practical
With its elegant all-alloy casework, the Masters M23 HybridDigital Stereo Power Amplifier is as pleasing to the eye as it is thrilling to the ears. The M23 has the same quality of construction for which NAD’s Masters Series is renowned. Rigid panels and magnetic iso-point feet provide a rock-solid foundation for the M23’s multi-layer circuit boards and intricate internal construction. Truly the M23 represents a new pinnacle in power amplifier design.

NAD is a respected audio brand with decades of engineering heritage, known for performance-first design and clean, real-world power delivery. Today, NAD is especially valued for home cinema receivers and processors that combine musical, controlled sound with modern features — including BluOS for multi-room streaming and flexible system building. If you want immersive cinema with clear dialogue, solid dynamics and a system that remains upgrade-friendly, NAD is a very sensible direction.
At the same time, NAD has a strong place in two-channel hi-fi: integrated amplifiers and stereo components that prioritise balance, drive and long-term reliability — without chasing flashy specs. Many customers start with cinema and later build a dedicated stereo setup in the same system philosophy.
Hi-Fi Market is an authorised NAD dealer in Estonia, supplying genuine products with official manufacturer warranty and local support. We help you choose the right NAD solution for your room size, speaker layout and listening habits — and we’ll guide you through setup, calibration, and sensible upgrades that bring audible value.
Visit our showroom near Tallinn (Tabasalu) to discuss a focused NAD-based plan and compare options calmly before you commit.
Build a System with NAD (Home Cinema + Stereo)
NAD components work best when you think in systems: start with the core (an AV receiver / processor for cinema, or an integrated amplifier for stereo), then match speakers and setup to the room. A well-chosen NAD system stays coherent and easy to live with — and remains a solid foundation for future upgrades.
Explore compatible categories for an NAD-based setup:
– AV Receivers / Processors / Amplifiers
