I completely agree with most of the posters here - adding Amazon HD would be a valuable addition to Roon. I tried Tidal, currently subscribe to Quboz, but find both lacking. I frequently rely on Amazon Music Unlimited and Apple Music when out and about in my car, for a walk, bike ride, etc. Having it integrated into Roon would be amazing.
So another +1 for Amazon Music HD being added to Roon! Now that I’ve invested in the Roon infrastructure and purchased a lifetime subscription, I’m all in. I’d hate to miss out on what will arguably be the best HD option currently available.
