Amazon music through the ultra app or cast from Amazon music ???

[Spoonman51]

I don’t see all the music I have on my Amazon music account when i open it through theWiim ultra app . So that being said does the music lose quality if I cast from the Amazon music app to the Wiim ultra or is casting it to the Wiim the same ???

WiiM devices play bit perfect whether you are using the WiiM home app or using AlexaCast from the Amazon Music app (or Alexa for that matter). The quality is identical.

Edit: note that if you use Chromecast from the Amazon music app, you’ll be restricted to lossless HD/CD quality. Airplay or Bluetooth will cast only lossy audio.
