my experiences …..it depends .
i do both with good results . . ETHERNET direct cable connection ultimately was declared a winner in my A system after I went full Monty with ALL of the following and Each step matters ,
In my lesser systems without the same audio resolution, wireless is fine
- high-end top end build and properly shielded Ethernet cables with TELEGARTNER connectors
- audiophile grade Ethernet switch,
- external linear power supply for the network switch, and
- Ethernet LAN filter.
