Good morning Jan, hopefully, you slept well (nobody was bothering you).

The differential amplifier improves operation and ripple rejection considerably, compromising on that would be expressively unwise. Adding an array of mythical fairy lights instead, of course, would not help at all.
Despite measures taken, the moderately clean voltage (in this context) at the base of T9 is obviously a weak point.

No, this is a series regulator.

A shunt regulator for a high powered Class AB amplifier would be a wasteful beast indeed. Pretty much equivalent to a huge Class A amplifier providing power rails for a Class AB. You may just as well build a Class A amplifier in the first place.
