Pass Labs, First Watt, SIT-3 is the very latest example of single-ended / single-stage Class A amplifiers using the SIT (aka VFET) power transistor exclusive to First Watt. It is preceded by the successful SIT-1 and SIT-2 and very much follows their technical philosophy and construction. There is a key difference in the SIT-3, which is that the Static Induction Transistor (SIT) that forms the heart of the circuit is operated in an entirely different mode, what is known as Common Drain Mode. The music smooth and has strong presentation and great timing with awesome detail and insightful delivery.
