I am used to Voltage Feedback design but wants to get into Current Feedback Design but their some problem.
Most CFA example i can find a diamond buffer based ,which are known to cancel 2nd order distortion , which are the last thing i want.
I want to start this thread so that i can get introduced to some CFA input state design. 🙂

CFA hybrid amp (MOSFET + BJT output). Excellent THD profile, sweet sound. Designed by Ranchu and AKSA.
USSA-3 and -5 versions are CFA amplifiers and have symetrical input stage but not diamond. H2 can be adjusted to desired level mainly by selecting proper positive and negative current in input stage (P3 and P4).
