NAD Masters M28: Purifi Eigentakt Amplification
The NAD Masters M28 features cutting-edge Eigentakt™ amplifier technology, developed under license from Purifi. This advanced technology, which NAD pioneered with the M33 Masters Series Streaming Amplifier, refines self-oscillating Class D technology by accounting for previously unknown effects of the output filter in the feedback loop. The result is near-theoretical performance in both low and high-power scenarios.

Unmatched Performance and Stability
Unlike most Class D amplifier designs, the M28, like previous generations of NAD Hybrid Digital technology, is unaffected by the loudspeaker load. It maintains a consistent wide and even bandwidth response regardless of speaker impedance and offers high current capability. With continuous power of 200W into 8 ohms for all channels driven simultaneously and 700W dynamic power into 4 ohms, the M28 delivers exceptional performance.

Analog-Like Clipping Behavior
Eigentakt™ technology ensures analog-like behavior in the rare event of amplifier clipping. Unlike many Class D designs that can become unstable, Eigentakt™ recovers instantly, similar to well-executed traditional Class A/B amplifiers.

Fully Balanced Audio
The M28 uses a studio-grade audio interface, providing the highest signal integrity with the lowest noise floor. Locking connectors and specialized interface electronics allow long cable runs without noise pickup or signal loss, ensuring pure, unadulterated sound.

Effortless Power
As NAD's most powerful amplifier, the M28 delivers over 700W into challenging loads, accurately reproducing complex dynamic peaks in movies and music. From delicate rim shots to powerful asteroid explosions, the M28 creates a remarkably real and immersive experience.

Advanced Technology at a Lower Cost
Thanks to the advanced Purifi Eigentakt™ amplifier technology, the M28 provides superior power and performance at a lower cost than traditional technologies. This makes it a cost-effective solution for achieving high-resolution digital soundtracks and unparalleled sonic refinement.
