Hi everybody. I imagine another amplifier with 0% distortion in LTSpice.
The scheme was created based on the scheme Hans Polak with a high-voltage operational amplifier OPA552 :

Hi. I present a circuit on OPA453. 100 watts. The distortion is greater than on the OPA552, but if you draw the board correctly and solder it, the IMD will not be able to be measured by existing equipment. THD - 0.00004% 20kHz in LTSpice.

240 W amplifier, 4 ohms on the ORA552 with a tracking supply voltage. THD 0.000003% 20k
