TV Room: Three (PS5, Nintendo Switch, Apple TV), all going into an AVR via HDMI 2.1. Airplay can be done via either the Apple TV or AVR.
Living Room: Three (Airplay via WiiM, Apple TV and Nintendo Switch via toslink from the TV to the WiiM).
I'm actively looking to replace the complicated living room setup (MiniDSP Studio for Dirac, WiiM as preamp, buckeye amp, toslink instead of ARC, and sometimes using the WiiM to switch sources, sometimes the TV). It's huge and a mess. I both love and hate the MiniDSP -- it feels like a device built for how we did things fifteen years ago -- no ARC, no wired remote control (all this stuff is hidden in a cabinet and can never have line of sight for IR or for seeing what the current source is), no auto switching (this is the worst for me). It's technically a great preamp. But in practice, using the WiiM is 100x better of an experience. And I keep thinking of replacing the whole stack with a single NAD M33 or something.
