Default THE DOUBLE WILSON VAS

the search for a voltage amplifier continues ... with Wilson

Fine, you have another pictorially nice, symmetrical topology to look at. Now, if you were to show comparitive simulations of other current mirror topolgies, it might have some significance as a reminder of what the textbooks say and show why such a current mirror might sometimes be used in analog circuits.

Default no problem

good to remember that the distortion is only one of the parameters that characterize the sound

Perhaps you misunderstand. I'm asking to see a direct comparison of say, the 3 common types of current mirror topology used in that OP circuit, #1 - so that that we can see what, if any difference, is visible in your simulation.

You have shown us your sim of the Wilson, now I think we'd like to see how others perform - in the same circuit.

In option 2 in amplifier to reduce resistors R9 300 ohms and resistor R12 is 10 kohms distortion reduced 2 times, i.e. to 0.025%.
the engineering and optimization has made by Petr
I can not say more
the project is open to the comparisons and improvements
