It never hurts to install dedicated circuits (more bang for amplifiers, but . . ) IF the house (branch) circuits you are using are full of noise from other devices on those circuits (lights, appliances, A/C.) Otherwise not.
Have you measured the AC voltage at your wall outlet? Is it 120VAC +3V and -0V AC, and consistently so, at different times of the day/evening? If yes, then power conditioners/regenerators are superfluous. And the only device that will both reduce noise and improve the performance of DAC's and other front-end and/or source equipment (if you want to spend the money) is a balanced power unit from Balanced Power Technologies, Equi=Tech, and others.
One generally reliable improvement for any DAC is a shielded power cord with (minimum) 12AWG conductors (DAC's love big power cords!) You don't have to spend megabucks, but it MUST have a shield.
