MastersounD - Evolution 845 - Integrated Amplifier (Class A)

The Evolution 845 is the culmination of the collective knowledge and experience of all those who work with MasterSound. The total absence of feedback makes the Evolution 845 fast, with imaging that is truly amazing.

Our new, dual drive control system of the Evolution 845 preamp section grew from our careful research. Combined with our unique output transformer and powerful 845 triodes working in Parallel Single-Ended mode, the amplifier renders a genuinely engaging sound.

We use a semiautomatic biasing system, which once regulated, will give optimal life to the final tubes. Finally, we use 24 karat gold connections on the Evolution 845 circuit board. The capacitors are either manufactured by high-quality for MasterSound.

Our philosophy is simple:
We produce amplifiers that arouse emotion, in which every note of music should precisely reflect the emotions of the composer and the performer. In addition to the technical excellence, our amplifiers satisfy the ultimate search for the life-like performance. Therefore, not only a perfect soundstage, focus, and dynamics are involved, but also a "spirit" quite rare in many systems - blend into the total synergy of your system.

The listeners feel immersed in the music and carried away through enjoying the life-like details of the instruments, in the most natural means possible... with emotion.

Mastersound amplifiers, except the tubes, comes with a five-year limited warranty covering defects in material and craftsmanship. During the warranty period, repairs are provided free of charge. Transportation costs, to and from, has to be paid by the owner of the unit.
