Just to add to the above, the WiiM Pro Plus and many other streamers will let you stream from a phone or tablet via Airplay 2 and Chromecast. Both of those options provide better sound quality than Bluetooth. You can also sign in to a streaming service like Qobuz or Apple Music and use the Wiim software to cue up streaming out to the digital output.
With the WiiM Pro Plus, you could even watch a Youtube concert video and stream the audio via Airplay 2 or Chromecast from your computer to the WiiM.
