Then why have you been on this site since 2005
chasing the wind?

on the basis of this it is possible to create a universal module for improving amplifier parameters, provided that we know the circuit's frequency response
I don't understand why you ask me this question both here and on message... I asked one polite question about the schema as I was curious to learn and now you harass me both here and there...
Why is the time registered on the site relevant in any situation? Other then possible when one is new and it would be prudent to take it a bit easy on the attacks.... !?
But maybe you have been registered before and banned and now you are here as "New Alex"...?

- why improve the parameters, because they are already good and it's just a waste of time.
Then my question is logical, or not?

Uh... Really? Have a look here: https://neurochrome.com/products/modulus-86-10th-anniversary-edition
Compare the performance shown in the data sheet with that of the LM3886 data sheet. Or if you want something that's even closer to an apples-to-apples comparison, have a look at the performance of the LM3886DR: https://neurochrome.com/products/lm3886-done-right It's measured on the same APx555B as I used for the Modulus-86. Same power supply too.
There's about 30x improvement in mid-band THD and more like 100x if not 1000x improvement towards the end of the audio band. That's likely why composite LM3886 amps don't have the "chipamp harshness" that non-composite amps have.
