well, the neurochrome presentation tries to show the best possible result, while the presenter here dares to show the worst case result.
Presenting in the same way, that is a full spectral display of the performance of the modulus amp at 19+20kHz --could surprise some here.
Showing here the most difficult case is just courtesy to the reader, directly cutting through to the heart of the problems.
The same for the time response plot.
having applied a 1nsec rise/fall time excitation without any input RF filters to a band limited composit loop -- needs courage & self confidance.
In that response one can observe as the system enters/ exit slew rate limit, and picks up the control with relative smoothness.

Both work the same. You can also use NE5534, LT1115, AD797, LM4562 or any similar one.
You are either blind or a psychologically unstable liar.
Provide concrete evidence for your outrageous lies immediately.
Notice that none of these critics have said anything specific to the point. People with supposedly 25 years of experience are writing psychological monologues without pointing out any concrete technical flaws
But, it is like trying a Ferrari on a landing strip..
Tom could have serious reasons of having decreased max possible performance in exchange for robust stability in real life. And a robustly stable system could sound much better at home than a finicky, but brilliant lab performer..
Why +_22V power supply? that's a serious limitation for an lm3886 amp..
also, ~18Vpp performance is nice to see, but max power lies around 60Vpp..
Then, I did not open yet the lm3886-ed spice model - what is the confidance level, are there real life tests validating, is it derived from the official model?

hmm.. it looks like You did not catch what i wrote, which was in your support..🤔
You should control your temper.. 🙂
Have a look at it again, take into account that my reaction was directed to TNT, and I tried to defend the method you presented your result..
But I can stop doing it, if you wish😜
He does not have any problem there. Note that there is a 1kohm series drop resistance for the opamp 'floating' ps. that is ~4V drop for the typical opamp bias current (opa1611 in schematics), from 22V that's in the zone of +_18V.
the official models L1875 and LM3886 are complete crap
