A streamer with only an Ethernet port does not require hard wiring.
Just get a wall wart WiFi extender and plug in next to the streamer.. then plug into that. $59 solution. Mine and many $100K systems work great off of that.
I have streamed, as you, have from PC, Macs, iPads… you want a dedicated streamer. Whole different category. My vinyl and streaming sound the same. You can see my system under my ID. But this can be done in different price categories.
