M28

The M28 is a reference-grade 7-channel power amplifier designed for high-end home theater systems that demand maximum performance and precision. Built with Purifi Eigentakt™ amplification, it delivers exceptional clarity, ultra-low distortion, and a highly controlled, dynamic sound presentation.

With 200W per channel (all channels driven), it provides consistent, high-current power across every speaker, ensuring effortless performance even in demanding multi-channel setups.

Unlike receivers, the M28 is a pure power amplifier, meaning it requires a separate processor or AV receiver (like a NAD T 778) to operate—making it ideal for reference-level systems where sound quality is the priority.
