IMHO you cannot have enough power. Get as many dedicated circuits that you have space for in you electrical panel. If you can use 10 Gauge wire. The smaller the number of gauge the bigger the wire. Use only copper wire. Use good plugs, minimum Hubble brand. Use 20 amp breakers if possible, This is not allowed if you are doing this with permits. Check with an electician. The outlet and plug have a different configuration by code. ( Everybody tries to get the most amount of power to their units therefore 20 amps). I am using 40 Amp 220 V for my 33's. In your breaker box (panel) try to have your digital gear on one side of the hot bar and the analog gear on he other side of the leg. Another thing to do is have a dedicated ground for each outlet. This is not a simple task but if you can it will make a big differnce, No noise from fridge,freezer,dryer,washing machine Air conditiong, ETC. If you need more info E-Mail me.
