I upgraded a turntable PSU to use active regulation instead of a simple zener shunt+capacitor and I cut the capacitance downstream of the regulator by 10x because it simply wasn't necessary with the active regulator on the job.
There may be some advantage to having the regulators on a separate board from a noise standpoint. With the regulators on a separate board you don't have any of the unregulated voltages present on your audio PCB. At a minimum I'd want the rectifier + it's capacitor bank/chokes/pi filters on a separate board if possible.
