Mastersound PF 100 Limited mono amplifiers

€30000 /pr

The PF 100 Limited is the culmination of the collective knowledge and experience of all those who work with MastersounD.
The total absence of feedback makes the Pf 100 fast, with imaging that is truly amazing.
Our new dual drive control system of the Pf 100 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.

Finally we use 24 karat gold connections on the Pf 100 circuit board. The capacitors are either manufactured by high quality for MastersounD.
