For me, features and stability are the most important aspects of a streamer (once it handles sufficient formats). I’ve used volumio and other Pi solutions, but my cambridge audio streamer/DAC just works, and the others are finicky, even when wired. If you are using wifi, this goes double.
With CA I can use Chromecast for multi-casting with my kitchen player and UPnP for single system play, and it switches back and forth seamlessly. I have a dedicated tablet, but I can use my phone if that is out of reach.
