There are a couple I looked that are just streamers ie: Network players and are very good. Lumin is excellent, Innuos more for usb DACs, and Esoteric which I ended up buying. All are excellent upgrades to the bluesound node. Incredible steps up I might add. On the budget side, the Lumin u2 is their new budget streamer, the older model u1 can be picked up even cheaper. The Innuos Pulse is also an excellent choice and their budget streamer. Esoteric is not really budget but a fantastic player. Hope this helps. If you’re interested in Innuos I have a friend in Minnesota who is a dealer. Good luck.
