Eigentakt™ Precision
The Masters M28 incorporates Purifi’s groundbreaking Eigentakt™ amplifier technology, licensed to NAD. This innovation ensures unparalleled precision, accounting for the effects of the output filter in the feedback loop and refining self-oscillating Class D tech. It achieves near-theoretical limit performance, delivering clarity and power, whether at low or peak volumes.
Impervious Load Handling
Unlike many class D amplifiers, the M28 remains impervious to loudspeaker load variations. It maintains a wide and consistent bandwidth response across different impedances, offering a continuous 200W into 8 ohms for all channels simultaneously. With 700W dynamic power into 4 ohms, this amplifier effortlessly handles diverse speaker setups, ensuring a reliable and powerful performance.
Analogue-Like Clipping Recovery
The Eigentakt™ technology ensures stable behavior even in clipping scenarios, resembling the benign clipping recovery of traditional class A/B amplifiers. This feature provides a safety net during intense audio demands, preventing instability and ensuring a smooth, controlled response, contributing to a secure and enjoyable listening experience.
Fully Balanced Audio Prowess
The M28 boasts a fully balanced audio interface, mirroring those used in professional studios. With locking connectors and specialized interface electronics, it guarantees the highest signal integrity and a minimal noise floor. This efficient design allows extended cable runs without compromising signal quality, delivering an immersive, noise-free audio experience in home theater setups.
