Description
The NAD Masters M28 Seven Channel Power Amplifier epitomises the ultimate in what is possible with today’s amplification technology. It is one of the very first amplifiers to employ Purifi’s Eigentakt™ amplifier technology.

Rated conservatively at 200W per channel (8 ohms) and well over 320W dynamic power (8 ohms; all channels driven), the result is breath-taking, lifelike surround sound performance, be it from the latest action-packed film with tremendous dynamics or a subtle classical piece with delicate and detailed passages. 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.
