I ran two independent 20A circuits for my system and one thing to consider is whether to put your circuits on the same phase or opposite phases.
I did the latter and run my monoblocks on one circuit/phase and the rest of my gear (preamp, phono stage, TT, DAC) on the other circuit/phase.
Some folks argue to run the same phase as it minimizes issues with hum, but I believe it’s best to run opposite phases - there shouldn’t be any hum issues if it’s wired properly.
My system is very quiet hooked up and wired this way.
