+1 for LUMIN if looking for streamer only. I have a U1 and it is very reliable, firmware is updated over the net, excellent sound quality. Is Roon ready but LUMIN software is as easy to use as BluO. I prefer Roon for a variety of reasons related to search capabilities, but sound quality of LUMIN software is just as good if not slightly better to my ears
Would agree with those suggesting spending some of your budget on Ethernet wire to the LUMIN. As others have suggested, add mesh wifi at a minimum. The mesh units have an Ethernet port for the streamer. Linksys and Eero make reliable units I’ve owned.
Happy listening.
