I agree with Rosceiii, consider a balanced AC power unit.I use a BPT that has 20 amp capacity and it is excellent.My entire system is plugged into it.I`ve had mine 4 years and it is worth every cent I payed for it.
Isolation of digital is vital to great sound.
I use separate balanced power isolation plus additional
conditioning for digital and the improvements have been incredible. My pre & amp are on separate isolation and conditioning for each. It's well worth it for the clarity, dynamics, transparency and nuance that you will "never" get without similar treatment.
