The JRiver ID for the RPi3 has only been available since Sept 2016. I only have one stereo system at the moment, but for someone with multiple rigs throughout the house these little devices would be my choice for highest quality accessing music stored on a NAS or PC. Currently, while the RPi3 has wifi, it isn't yet supported by JRiver so an ethernet cable is the connection. I don't know why this would be the case. I suspect they will utilize wifi sometime soon. The only thing that I miss a little with this setup is that I can't stream from Tidal with my Multibit DAC without pulling the USB plug from the RPi3 and move it to my PC, but that isn't really a problem as I have my other DAC a non-multibit Modi that is ready and tied into another aux on my pre amp. I suppose this would be where Rune really shines. As I understand it, it will stream from Tidal and access your drives and integrate both seamlessly. Not sure if that functionality extends to Rune for the Raspberry or not, but if true, that would be pretty impressive. However I dislike subscription software, and I really don't use my Tidal account enough to where I feel I need it.
JRiver is so well supported and I wouldn't be surprised if they don't move in the direction of streaming too at some point.
