NAD M28 Multichannel Power Amplifier
5999,00 €
The Masters M28 7 Channel Power Amplifier epitomises the ultimate in what is possible with today’s amplification techonology. It is one of the very first amplifiers to employ Purifi’s Eigentakt amplifier technology. The M28 can accept both balanced and single-ended inputs, and features high-quality binding posts for speaker connection. The compact dimensions of this highly energy-efficient design belie the massive amount of power available for the most demanding music and movies.
Purifi Eigentakt Amplification
The Masters M28 uses Eigentakt™ amplifier technology, manufactured by NAD in license from Purifi. This new technology, which NAD was the first to embrace for the M33 Masters SeriesStreaming Amplifier, adds another level of precision by taking into account previously unknown effects of the output filter in the feedback loop and further refinement of the self-oscillating Class D technology as used by previous NAD Hybrid Digital designs. The result is a performance level that approaches the theoretical limit in measured performance, be it at whispering levels or at full power.
In common with the previous generations of NAD Hybrid Digital technology but unlike most class D amplifier designs, the M28 is impervious to the loudspeaker load it is presented with, maintaining the same wide and even bandwidth response irrespective of the speaker’s impedance and at the same time providing high current capability. The continuous 200W into 8 ohms on tap for all channels driven at the same time and 700W dynamic power into 4 ohms is testament to this.
Inherent to the Eigentakt™ technology is its very analogue-like behaviour in the unlikely event the amplifier is driven into clipping. Whereas many class D designs can become unstable, Eigentakt™ behaves in a way similar to the benign way of clipping with instant recovery of well executed traditional class A/B amplifiers.
The sonic character of the M28 only reinforces the story told by the numbers. This is an amazingly powerful and transparent amplifier bringing new levels of refinement and dynamics at any level.
Fully Balanced Audio
The same efficient audio interface used by studios provides the highest level of signal integrity with the lowest noise floor.
Locking connectors and special interface electronics allow long cable runs without noise pickup or signal loss. All you get is awesome sound without the possibility of noise pickup or interference.
Effortless Power
As our most powerful amplifier ever, the M28 can pump out over 700W into difficult loads to follow complex dynamic peaks in your movies and music. Everything from rim shots to asteroid explosions sound remarkably real and immersive.
The M28 has power reserves to meet the demands of the latest high-resolution digital soundtracks. Thanks to the advanced Purifi Eigentakt™ amplifier technology, all this monster power comes at a lot less cost than traditional technology and delivers more power and performance!

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
– Home Cinema Speakers
– Integrated Amplifiers
– Stereo SpeakersIf you want a quick shortlist, contact us — we’ll recommend a NAD-based setup matched to your room, budget and preferred listening levels.
