The 845 Monoblock is the culmination of the collective knowledge and experience of all those who work with MastersounD.
The total absence of feedback makes the 845 Monoblock fast, with imaging that is truly amazing.
Our new dual drive control system of the 845 Monoblock preamp section grew from our careful research.
Combined with our unique and powerful output transformer, 845 triodes working in Parallel Single Ended mode, the amplifier renders a genuinely engaging sound.
We use a semi-atomatic biasing system which once regulated will give optimal life to the final tubes.
The capacitors are either manufactured by high quality for MastersounD.
