BluOS supports HD Amazon. Once you have the latest software on your control device ( I didn’t) ....it allows all supported Resolutions. The Bluesound Node 2 or 2i are relatively inexpensive, especially in the used market. Initial observations are that it sounds at least as good as Tidal.....perhaps somewhat more dimensional and detailed and more “Alive” sounding.....Tidal can be somewhat soft and a little laid back sounding.......
