Just a note, the L-R connection does not use WiFi / internet. The connectors and the cable are identical, but that's where the similary ends. The only reason to use the cable is if you want to use 192khz, since the wireless connection is max 96 khz.
I guess it's possible, but it's probably bad for business. Proper blind testing and scientific measurements will make the make market more efficient, pushing consumers to buy lower-margin products.
