Hi Scott,
Yes the combination is fantastic. I’m really enjoying it. I too would love to get Roon to work with JPlayStreamer. I was hoping this would be possible as Roon seemed to be working with Linn a few months ago and of course JPlayStreamer uses the Linn sponsored OpenHome protocol. However it seems from some of the discussion here on this thred that Roon will not be supporting OpenHome and also have also run into issues supporting Songcast. Linn was one of their hardware partners but it seems no longer.
