The high drain devices such a bluray, SSD, additional optical Dac will be powered from the 7 port powered hub below the PI. The hub will get a 2 or 3 amp regulated 12volt to 5 volt supply.
I have an additional 12 volt power distribution block nearby which I use for switching on my additional audio equipment ( amps , DSP , old car pc) The power is controlled via the state of the bm53 aerial and amp out.

I may need to change the shutdown timers on the PI so it isn't left with trying to drive the hub in between. ( I haven't studied your power supply to see if I can tap in somewhere to control a relay for the power to the USB hub based on state)

Old system
