I second using pass transistors. I would hesitate using any standard
regulator, and by using resistors to balance the load between
regulators, you negate any benefit regulation might give you. Why don't
I like regulators?  Current limiting. Nearly all of them do it. A simple
zener referenced pass transistor sounds better and an IC voltage ref.
ought to be better still.

If you want to try hearing the degradation resistors cause when they
are on the rails, bypass your rail fuses with wire. Yes, if you have a
problem in the amp, you could lose the output devices, but I run
my amp that way and it sounds much better.
