The Masters M28 Seven 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.
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.
