Hello,

I am upgrading to a new system and after much digging and researching, I have come up with a plan and would like some advises on my setup and controls. I would like to simplify the setup if possible, and please let me know if I am missing crucial components or I am doing things that aren’t recommended. My use case will be 70% music 30% movies. I am planning to turn on/off equipment with a standard power bar with surge protection and a remote-control electrical outlet. See diagram below.
Below is a list of current equipment I own, purchased used and planning to buy.

Planning to buy:
DAC – Schitt Modius
PowerAmp – Schiit Vidar
DSP – miniDSP 2x4 HD
Cables and wiring – Blue Jean speaker cables

Purchased used and on their way:
Speakers- KEF LS50s
Subwoofer - 1x Rythmik L12
Pre-amp – Schiit Saga

Already Own:
Chromecast Audio, Fibre splitter 2 in 1 out, TV, Nvidia Shield

Operation:
1) Chromecast audio-> DAC-> pre-amp->miniDSP->power amplifier & subwoofer
2) PC (plex) -> Nvidia shield -> TV -> DAC-> pre-amp->miniDSP->power amplifier & subwoofer
3) PC (plex) -> Nvidia shield - USB to DAC not sure if this is possible

Questions
Q1) Are the wiring done correctly, especially from DSP to subwoofer?

Q2) Would using the remote-control outlet damage equipment such as DAC and power amps?

Q3) If I take out the pre-amp and DAC out of the system and use the miniDSP DAC, how is the volume control via Shield->TV-> miniDSP DAC?

Q4) I’m currently using the fibre splitter to switch between Chromecast Audio and Shield seamlessly by connecting & disconnecting from Android phone. Are there better solutions that would improve the sound quality noticeably? I’d imagine the optical signal is digital so there should be no losses from the $10 dollar splitter.

Q5) Is It possible to add a third LS50 as a centre speaker to this setup? All the outputs of miniDSP are occupied, or could I split output 4 to two subwoofers simultaneously (given the subs operate in the same settings)

Q6) Any tips on making operation 3 to work? This way the TV could be left off

Thanks a lot in advance for any advice!
