but to come back and nail down your question a bit more. In my reference system I have essentially 3 dedicated circuits back to the panel for audio: Low level analog w power conditioning, Digital wall warts, server ( even w linear supply as it has no Faraday cage ) , streamer, network switch all on a seperate line and power conditioning, finally monoblocks w no conditioning on a third line ( split from 240 ).
