Why don't you look at the HEC or Cordells error correction. I do believe that most of what you're trying to cure is the poor performance of your output buffer. Some kind of feed forward Error correction could make your concept fly... What kind of performance do you have with high signal on the voltage gain stage alone.??

I used HEC, look here ODNF or no GNFB power amp. Voltage gain has quite low distortion, main distortion is comming from output stage.

Ohh sorry I did not see that... What about Cordells feed forward error-correction, would that yield better results... Somehow it would be nice to get the opamp out, as in all the opamp-argumented feed back soldering I have done it's impossible to thame.

What is different between HEC and Cordells feed forward error-correction. Could you direct me where to look in his book?
