Description
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.
Fully Balanced Audio
The same efficient audio interface used by studios provides the highest level of signal integrity with the lowest noise floor.
Locking connectors and special interface electronics allow long cable runs without noise pickup or signal loss. All you get is awesome sound without the possibility of noise pickup or interference.
Effortless Power
As our most powerful amplifier ever, the M28 can pump out over 700W into difficult loads to follow complex dynamic peaks in your movies and music. Everything from rim shots to asteroid explosions sound remarkably real and immersive.
The M28 has power reserves to meet the demands of the latest high-resolution digital soundtracks. Thanks to the advanced Purifi Eigentakt™ amplifier technology, all this monster power comes at a lot less cost than traditional technology and delivers more power and performance!
