Bryston BDP-3, WiFi vs LAN cable for streaming

[Parabellum]

Hey,

Just purchased a BDP-3 but it does not have the optional built-in WiFi module. I always used my prior BDP-2 with the internal hard drive for play back but out of curiosity I recently registered to Tidal and Amazon Music and I would like to get the best out of those services. In my understanding, going WiFi would eliminate any sound degradation altogheter due to the absence of LAN cable. In my setup, my modem/router combo is about 30 feet away from the BDP-3 so any audiograde LAN cable is out of the question.

Question is, how much sound quality would be affected using a regular LAN cable for streaming? How important is this cable in the audio chain?

Thanks!
