Ethernet is the best transport medium, either WiFi or wired, for audio data.
This is a system-thing, not a device or protocol thing. Some systems may be sensitive to RFI, but for other reasons. In particular, ground-loops provide very nice loop antennas to pick up RFI. HF currents in these ground loops can be audible. Get rid of the ground-loop antenna and you will likely have no noise from RFI. To assume that RF affects all audio systems is erroneous.
My system has no ground-loops, so RFI has absolutely no effect, and my personal system is one of the most resolving systems on the planet.
