you dont need any advise, that looks very good and logical in my eyes.
In this matter I have some questions:
To picture No. 1: Are the signal cables together with power supply cables in the multicore cable? If yes I would separate the signal cable from the other.
To picture No. 3: You dont need the RCA input jack if you dont want to use this cable in future. You can desolder it if you want to use a simple short but shielded internal cable.
To picture No. 4: Thats the best way too. The isolation of the caps from the input site is absolute correct in my eyes.
Good work, my =D>
