SS amps with little or NO feedback


I'd like to explore amps with little or no feedback.
Global feedback is a no-no but some feedback a stage at a time may be acceptable.
Any names to look for? Since I want higher power, class 'a' need not apply.

There are enough theoretical problems with my 'd' amp that I'm seriously considering a 'sidegrade'.
thanks for any leads.

Kijanki, if it is a true balanced differential design the main harmonic created will the the 3rd, not the 2nd. All the even orders should cancel. This is true of tube or transistor designs.
