I am giving the 90 day free trial a go and so far Qobuz smokes Amazon Music HD in sound quality.  Amazon is crippled because it uses Windows sound mixer in shared mode, exclusive mode is not an option. Neither is Roon or Audirvana integration.

The best streaming sound quality I have on my desktop rig using a Yggdrasil DAC is playing Qobuz through Audirvana+. Audirvana uses Wasapi exclusive mode and sounds a bit better than the Qobuz desktop app.
@duckworp,I did read that Chromecast compatibility in the FAQ section, and it is sad that through Chromecast, only standard streaming, not the CD or higher quality.

Going to wait this one out for a bit.
Was very dissapointed with Amazon last go around.
Word so far is that this relaunch is not quite as rosy as they say.
Big surprise.....
Not!
