Jung is quite right (at maximum), Curl does not show any relation to output power (or voltage swing).
True......i asked why, and got no response....

And I should add - the positive slew and the negative slew should have the same speed.

True........easthetically pleasing.........
by what means do you ensure such symmetry in your designs..?

One of the reasons is too maintain very low distortion even at high frequencies

Symetrical slew rates are important, as is freedom from 'stiction' when coming out of clipping.
Distortion at high frequencies is not so nearly as important.
0.1% distortion at 10kHz is inaudible.

In case that you speak about 1-tone monaural sinus tone then I agree.

I'm in again. Couldn't help it.

A fast, (>100V/uS), voltage-feedback driver.

How does a 10 V/uS LH0101 qualify as fast, or are you just
playing with us?
