Streaming: WiFi or wired??

Most equipment manufacturers will advise to use a wired connection if the device can do both and you have a choice between the two. Everything being equal, the best a wireless connection can do is be as good as the wired connection. It will not be better. If that’s the case, the wireless is definitely more convenient. Keep in mind that the wired connection will always be more robust.

In my experience, wired has always sounded better, except for one product, the Auralic Aries Mini. There is however a fundamental flaw with wired Ethernet, it acts like a long aerial that, in addition to passing your data, picks up RFI/EMI from your local environment.
In my opinion a good RFI filter is essential. The ENO by Network Acoustics is cheap and transforms the listening experience. Link to their site here https://networkacoustics.com/

"

it makes no sense to run ethernet cable in your home that is rated higher than the cable used for your incoming service."

Wish I'd thought of this obvious fact before buying a fancy ethernet cable. Oh, well. Surely it's doing no harm (?)

Hopefully one day your service will catch up.I'm  100% in favour of wired.No chance of interruption with other signals. The cable lifters are a nice touch though.

Not every wi fi component is a snap to get on the WiFi system...with wired you don’t have that issue.  I also think a wired connection is less prone to dropouts when you have competing WiFi devices , like refrigerators, etc. gobbling up the available bandwidth.
