I have compared WiFi with a short ethernet lead direct from a mesh extender and ethernet over mains -(a plug adaptor sits in mains circuit and a short ethernet lead goes into back of streamer)
A big jump in quality from WiFi to either of the ethernet options, no interruptions and quality of streaming improved. That said this WiFi streaming was always from a phone - I imagine a dedicated device like ipad/laptop just for hifi may improve this.
Some of my stored music is hi res and the differance between that and streamers like tidal masters still gives edge to stored material... Just my thought
