Default RMI-FC100, a single stage audio power amplifier

This is my latest amplifier design. For me, the quest of finding the best sounding amplifier is over.
Firs of all, I want to thanks to MikeB and JCarr, they was my source of inspiration and to Mr. Nelson Pass for a key advice regarding folded cascode topology.
This amplifier has borne as a freeware project and it is dedicated to this marvelous community of enthusiast people that adhere to share knowledge and experience.
I'll start with few pictures. Tomorrow I will continue with specs, amplifier schematics and front end regulated PSU.

For normal listening levels, 2W A class is enough. The amplifier is optimally class B biased.

Amplifier topology.
