The Mastersound PF100 Litz Edition is a flagship Class A monoblock tube power amplifier, built according to a parallel single-stroke triode circuit with four 845 lamps and three 6SN7 lamps, producing 1×107 watts at 4 or 8 ohms.
Due to the complete lack of feedback, this monoblock features an unusually wide, deep and balanced sound stage. Achieving the highest sound quality is also facilitated by the most meticulous selection of individual components: according to the criteria of the highest quality, reliability and availability over time.
Like all amplifiers from the Italian company MastersounD, the mono power amplifier operates in pure Class A (Parallel Single Ended in classe “A"). The 300B audiophile lamps work in the output stage, and the output transformers for them are designed and manufactured manually in our own factory.
