Apartment Stereo Install with Onkyo TX-NR696

I have an Onkyo TX-NR696 that needs to be fully integrated into my apartment for a dedicated stereo setup. The goal is simple: enjoy clear two-channel sound from my TV, a vinyl turntable, and any Bluetooth source without a tangle of wires cluttering the room...
