This is a threat for Tidal and MQA … and for Roon in the case the Amazon integration will not happen. Currently I am using Qobuz and Tidal, but Tidal only if an album is not found in Qobuz. With Amazon available in Roon I most likely will go with Qobuz and Amazon. If Roon should lose all streaming services I will return to JRiver, which I still use to maintain my large music collection including personal 5 star track ratings.
