according to Wikipedia, Yageo and KEMET are one corporation, Jamicon is not mentioned at all https://en.wikipedia.org/wiki/Yageo

I acquired them for these comparisons on purpose

Looking at the new one, the OPA is practically weaker than the LME in everything.

Because it is. I did comparisons on the dual OPA and the entire LME series. These are good op amps, but OPA2134 has long been referred to in the West as a good entry-level opamp for audio applications. Now you should probably take e.g. LME49860 (or the neighboring models) and the LME49600 buffer at the output.

I have an LME49860 at home, and my colleague "FIMEK" claims that the OPA134 has almost cosmic parameters, it is dedicated to headphones and it is much better to use it as a headphone amplifier.

Invite the topic page. There is a detailed description of my amplifier and the elements used in it.

OK, my mistake, I fixated on the presented diagram, where there was NE ... and not LME ... Now it remains for me to ask what these distortions are after equipping the opamp with the power stage? You write that small, which is probably true, but what?
