I stream on 2 systems with Roon. On the second system I just took an old retired laptop and put roon on it for the endpoint. So once you have roon, all you need to come up with is a computer/raspberry pi, node, or other roon ready endpoint for each system to act as the streamer. Most of the work is done in the Core so the device used at the remote system to stream can be a very simple (old and weak) computer.
Thanks @carlsbad , I'm a complete newbie on streaming, so I'm not familiar with roon or what it does. I've used a tablet playing over bluetooth before getting my Node 2i, so I was thinking in terms of how the Node works, with Tidal and my own digitized library trying to replicate that although I'm not completely satisfied with the easy of artist/album selection from tidal.
May I suggest trying our Vera-Link which offers up to 5 different separate Listening Zones Very affordable 50 watt per channel Wireless Streaming Solution https://verafiaudiollc.com/products/best-audio-products/vera-link-53126868
