Any unit that can act as a Power Condition + UPS?

Do you use a receiver?

An audio receiver? No, but I might use one. What are receivers for again? My consoles will all be outputting digital sound via HDMI or TOSLink. I have an Extron Crosspoint that has 32 video and audio inputs/outputs in the form of BNC and Phoenix Connectors.

A receiver, in the most general sense, is a radio with a built-in amplifier. Where it concerns video and home theater, AV Receivers (AVRs) will have the radio, amplifier, and multiple analogue and digital audio and video inputs, with newer/contemporary ones supporting features like ARC, Bluetooth, 4K, and network functionality, like media servers and internet firmware updates. An AVR could very well replace a 4, 5, 6, or 7-port manual HDMI switch.

For example, I have an Onkyo TX-NR555 (somewhat lower-end, and recently discontinued), which has a mix of digital and analogue audio and video inputs, all of which can be assigned to one of six or seven presets, selectable from the front of the unit and the remote (and supposedly automatically with HDMI-CEC, but my current TV doesn't support it).

Just keep in mind that, if you have an OSSC and want to use a mix of TOSLINK and analogue stereo sources, you'll need to either bypass the OSSC altogether for audio (requires either limiting yourself to a single input on the OSSC, or something creative, like using an HDMI splitter and multiple inputs on the AVR) or, if you prefer to have your OSSC switch analogue audio and run TOSLINK directly to your receiver, have one profile on the OSSC with TX Mode set to HDMI for your analogue audio sources and another profile with TX Mode set to DVI for your digital audio sources. (Would be really nice if the OSSC just had TOSLINK inputs.)

Power conditioners are somewhat glorified power strips, but sometimes they can help for crt's as crt's are a bit more sensitive than other video related equipment at picking up noise, sometimes it's so fine you wouldn't even see it, so yes maybe the usefulness of such a device will really vary on a per case basis.

Would be nice if the OSSC had quite a few additional things, like HDMI input, S-Video input, RCA Stereo inputs (oh well, on this point it can at least take audio from the SCART input).

Power Conditioners do make a difference, but if you want to see a bigger difference you need to pay ALOT more money on units that compltely cleans the signal.
