Well, I was thinking of using discrete voltage regulators to regulate the psu for both my pre-amp and power-amp, but was wondering, for the preamp, would I be better off with a discrete voltage regulator circuit or an IC by national or the likes? And for the power-amp, would an IC coupled with transistors to increase it's current output be better then a purely discrete voltage regulation circuit?
I'm betting I'd be better off either way with the solely discrete setup. But I was looking around for circuits, but I really haven't found any that suit my needs, I need +/- 24V for my preamp and +/- 28V for my poweramp, I can find lots of ideas on using opamps with transistors for +/-15V, but nothing with solely BJTs (which is what I'd rather). I can make one up using zeners and BJTs, but I'm looking for a circuit that's really no-compromise, doesn't matter if it's overkill (in fact that's what I'm looking for).

Well, there's been lots of discussion about this. Start with this recent thread, then look up some of the keywords for more:
