Logitech Media Server with an appropriate chromecast bridge plugin. Qobuz content can be casted with 192 kHz quality. Of course it's pretty academic to use it instead of 96 kHz.LMS?
Personally I wouldn't want to use Bubble UPnP. I've used DLNA to stream video from my PC to TV so know about it. But for mainstream usage I'd just want to cast from the official apps.
