@designsfx I can’t speak to the improved sound “quality” of streaming but I had previously suffered continuous dropouts and stuttering (for lack of a better description) which was driven by the router. When changing equipment I had been advised to use extenders (Powerline) as opposed to mesh but it was the router that made the real difference (using Amplifi Alien). The extenders have worked out great.
Power lines work for network but doees not fear well for the turntables. I heard quite loud packet clicks through the phono stage. Removing power extender removed the clicks. For streaming I use wireless extender (although it does degrade the wireless network somewhat) connecting it via cable directly to the streamer. Later solution seems to be working better in my case.
