Oh, my... Man you haven't learned anything useful in all these years? It's JUST another complex thing, wasting time and effort for another zero in thd percentage no man in the world can hear.... 😕
If you want to challenge your self try to do it with half the parts at least.

I really liked this VAS
Distortion is negligible
The spectrum is very short with a predominance of the 2nd harmonic
speed distortion is absent

You can't call it VAS, it is whole input gain block, using current conveyor with added output buffer because EC needs low output impedance to drive it as pure current conveyor has quite high output impedance.

I am curious, to whom you pointed this comment?

dadod, this version of the voltage amplifier is not the best option

So you like it but not the best option?

I doubled the GST currents (from 2 mA to 4 mA)

So you doubled CCS current and now is better, just so, without any proof and explanation. By the way what is GST? It will be nice if you use standard English abbreviations.

typo - generator constant current (GCC), or GSC - generator stable current
