The video thing may influence audio decisions for compatible gear....but with so little 8k content, why bother or are you a gamer? 4k is still relatively limited. I don't think your current gear particularly lacks in audio quality, but perhaps in usefulness/connectivity. Do you really find a great difference between Spotify's lossy codec and a lossless one? Have you tried testing yourself on the differences of such? If you do try a lossless service, does it have the convenience of Spotify? I tried both Tidal and Qobuz and simply stuck with Spotify, but I don't rely on Spotify for my library, but have a large ripped cd library available for streaming at a slightly higher quality, I don't find hi-res to be particularly "better" unless the recording is simply better. Mostly I use Spotify to find things to add to my own library (largely cd based but also multich sacd, dvd and blurays) but having Spotify on so many devices makes it so much easier to use (but I have multiple systems as well). The newer Atmos services might be interesting to stream and a modern avr just might be the ticket for both multich/digital flexibility. I simply use my laptop/phone/tablet to direct streams at my gear rather than use a dedicated streamer.
