My wife... does not have audiophile ears. Maybe some of you can relate to this…
I totally relate. It’s not that she doesn’t hear; she also doesn’t care.
I used my MacBook Pro for streaming, with a Halide Bridge through USB to Dac. Realised this had a ceiling, and eventually upgraded to a streamer. Does your streamer connect via wifi or ethernet? Ethernet is better. And if looking at next steps, an audio network switch would improve things even more.
