I beg to differ, @PMA
There are a great many threads of projects that started without building.
I have posted a few such threads.
And some people will like it and build together.
Now @PMA you do it the other way. You have the opportunity to build and publish. That's fine.
I have no possibility to build.

I will post squarewave 10kHz, too.Now that's as square as it gets!
But the upper bandwidth is only 400kHz.
On the other hand that can be good for to make a stable amplifier.
Yes, with 2 x 35V supply it should be possible to stick with one pair. With 2 x 55V supply I get 2 x 250W/4R and 2 x 150W/8R and the amp starts to be quite complex, if I want to stay at a safe side. But it is a dominant pole compensation, not TMC.

Sims have to provide enough info. Square wave in & out doesn't. What matters in that case are the waveforms within the feedback loop which might reveal clipping / overshoot. The AC voltage over R13 would provide that info.I beg to differ, @PMA

Looks classy. Fun stuff!Yes, with 2 x 35V supply it should be possible to stick with one pair. With 2 x 55V supply I get 2 x 250W/4R and 2 x 150W/8R and the amp starts to be quite complex, if I want to stay at a safe side. But it is a dominant pole compensation, not TMC.

Have you tried two pole compensation?
I did, in another projects. It improves distortion at high frequencies, but it makes stability a bit worse, even if you have "enough" stability margin in loopgain analysis. Audibly, it brings nothing, there is no difference. After decades in this hobby, I do not believe any sighted test opinion. The test must be properly done double blind, with perfectly matched level, to have some significance.Have you tried two pole compensation?
Why write 0,000%? It could be 0,00099 which means that it is 0,001 really.
It is a simulation - and as such VERY uncertain - to play with decimals leaving the actual value out, pretending that it is 0 (?) is silly - nobody here is fooled by that - you must realise that. Be open - play no games.
