FWIW I have been using either hard drive media or streaming for the last few years and left my CDs in storage since moving over a year ago. I started with my own rips and FLACs and still prefer those to streaming when possible, but the majority of my listening is streaming. First couple years were Tidal because Qobuz was horribly unreliable for me here in the States but it's been better lately. I still subscribe to both services as well as Spotify for convenience/catalog and since it's a relatively small price to pay for so much music (plus I hope it helps artists even with the pittance of royalties). Dropouts and noise are exceedingly rare for me and I never get any weird distortion - that sounds more like a potential software/hardware issue with the Bluesound? I'm interested in getting a Powernode (just got one for my brother) so I hope they are reliable.
I usually have my streaming DACs/endpoints wired with Ethernet but have used a WiFi bridge without issue. My network is admittedly pretty solid with Ubiquiti gear and usually gigabit broadband but I've operated fine with lower service levels. 100mbps is more than sufficient unless you are simultaneously streaming 4k UHD or have tons of clients (e.g. kids as someone pointed out).
