David, thanks for posting. I'm hoping Amazon has a deep catalogue and the GUI is easy to use. I have a Lumin T2 streamer dac and expect Lumin will update their software so I can access.

@tuberist  The catalog rivals Spotify's catalog. No MQA (that I know of). The key (for us) will be how the different services adopt and integrate it into their systems. In my case, Roon.
