@curiousjim It is not your ears but it may be your neighborhood!! :)
A good Wifi signal can do justice to any music, but wifi signals do go bad. I’m lucky enough to live in a detached home with excellent wall to wall signal coverage and no channel conflicts with my neighbors.
When I lived in an apartment complex I was not so lucky and every channel on either band was swamped. Some of those problems were made worse because of the Xfinity routers which put out separate SID’s for their mobile service in addition to the one you paid for, so twice as many signals would be out per router.
I'm also lucky enough to have a dedicated Ethernet from my data closet to my TV and entertainment center as well as my work PC, and I absolutely use it.
