I use a product called: Furutech E-TP60/20. It's a 6 outlet case with 12 ga wiring and 20 amp receptacles, even comes with one of their nice power cords. (Google for more details). They make similar units less in price that may work for you also.
I plug my Pass XA.5 amps into the wall, my preamp and tuners (have several) into the Furutech.
For digital, you could use one of the Furutech outlets and hook up something with a "digital filter" but I'd try it without and see what happens.
