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.

I'm not sure what you mean, but if I guess correctly your question, the load for those led's is the supply line for reference CCS of input stage.

SHUNTIE !!
It has very good behavior at HF and it is very quiet.
Much much better than a normal series regulator.
Why have you use a diode bias instead a more common Vbe multiplier, and could you give as some spec, like OL, CL, DF, etc...

those are diodes implemented in output bjts
lookie - 4 legs ....... almost as toob 😉

D1 is there because of tempco?
also 2SC3423 .......... there are here because of noise and temp. behavior ?
tnx.
