Why worrying about the capacitances, the gain of the transistors
or anything else,
the important thing is to choose either the feedback mode
or the appropriate compensation (TMC, LMC, PPC, NSC ...), so it goes.

Dear Cortez .
I have been in this forum since 2013 and there are many people who know
what is really important in audio amplification,
it is not only this topic but other similar ones, but the debates are usually sterile and short.
Any post for a poor 1w audio amplifier has more response and insights than those. BR
And there are some who are interested in this topic (really) but do not have enough knowledge. Like me. 🙂
Well the concept is not difficult to understand,
another thing is to interpret it in the electronics of an amplifier. Imagine a stage where there is a musical concert,
and it moves repeatedly and randomly from back to front,
from right to left ... the transmitted sound would be annoying,
and after a few minutes I assure you you get up and leave.
Why? because the sound information would arrive distorted in time.

I saw somewhere earlier that there are dedicated programs to distort wav files with every kind of distortions "numerically".
If there is such a program we could check this effect even at an exaggerated level (10x times as simulated above) just to check it with our ears.
Does somebody have some access to such program maybe? I guess it could be very usefull.

With the attitude that is glaringly obvious from the above post you probably won't receive much audience.
But you could start by fixing the title to something less foolish.
I am not here to receive much audience but to learn, after 7 years the truth is that it has been little but not null, there are people around here who know a lot.
The rest is your interpretation, not my intention

@ Ramcres. Believe it or not, there is a Hungarian engineer who is walking on a very similar street (maybe same?) like you. He developed a family of amplifiers, for the first time only on DIY line, but in 2019 these was already shown on the Warsaw High End Show as a standalone product. So you are not alone. The problem is that it is very difficult to accept the new aspects. There is nothing wrong with that, it is an essential human trait.
"Sounds" good! 🙂 Features:
- Harmonic distortion (THD, SINAD, THD+N)
- Different noise floors and various spurious noise components, such as mains frequency
- Various types of jitter, random, correlated, 1/f noise, and at various frequencies
- Dynamic range compression effects
- Different types of dither and bit settings
Audience includes also the people around here who know a lot. How would they know about this invaluable thread if the title is so misleading.
The concepts are not mine, there are many prestigious people from
very successful brands who warned us about them for a long time
I have only understood them and put them into practice. There is a phrase that sums up what the world of amplification is and it is:
"In the audio there is nothing that escapes the perception of the human ear". And I think it's true.
"Significance of time and phase errors for amplifier sound quality" or something similar would be better.
In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter.[1] Jitter is a significant, and usually undesired, factor in the design of almost all communications links.
One thing is the theory, and another to demonstrate it, is my claim. It has been known for a long time that there was something more than
harmonic distortion in the perception of sound but
I have not seen anyone put any evidence of what the cause was.
