MastersounD - 845 Monoblock Amplifier - Class A (Pair)

MastersounD - 845 Monoblock Amplifier - Class A (Pair)

MastersounD - 845 Monoblock Amplifier - Class A (Pair) 


The Model 845 Monoblock is a final mono amplifier in pure Class “A” which enhances the technical evolution of the famous triode 845. The output transformer we designed and manufactured for this triode allows to reach a range of extension which would be otherwise impossible with the use of standard output transformers which need work with a negative reaction. The result is a perfect sound stage and a surprising presence.

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.
