It does faster anyway it goes max positive to max negative AND BACK AGAIN at 20kHz. So first double that slew rate. Plus a significant part of that time it is going much slower. You need to be looking at the speed at the zero crossing point When the slope of the sinewave is steepest.

So the Pa5 can put out 29V peak (A is 29, 53W unclipped into 8Ohm)
so slope is 29x2xpix40,000 = 7.3V/us (Pa 5 is more or less flat to 40kHz - and actually goes up to 60 or 70kHz, so the real figure will be still higher.)
Someone please correct me if I've messed up there at all.
