Not much discussion about sound quality of Amazon Music HD. At present it streams to Windows app using the audio stack in shared mode, and SQ is inferior to Qobuz. Disappointed the developers did not enable Wasapi exclusive mode as Tidal and Qobuz have. I signed up for the 90 day free trial but have given up listening to it, staying with Qobuz until they offer exclusive mode, if Amazon ever does. Even though they are advertising streaming up to 24/192 it does not seem audiophiles are their target market.
