Hi-End single-channel amplifier board Amati Solo AS 5350I v2.1 with MOSFET output transistors can operate both in the inverting and “tube” modes, producing dynamic and realistic sound images. Differential input stages of power amplifiers are placed on the matched amplifiers for the amplifier cascade balance. No feed-through capacitors are used.
Listen to the tube sound without distortions!
