@joes44 you have to take another look at your setup.
Start with the source - You need high quality material (Tidal or Qobuz).
A streamer - in your case a one box streamer/dac solution like the Bluesound Node (latest) will be great. You can hard wire it or use its wifi. People tend to underestimate the Node. It’s really much better than most people think.
Using computer as a streamer, I guess it’s fine when we’re talking it’s in a context of a low end set up but even then you’re better off with something like the purpose built unit such as Node.
Worry about cables later. When you graduate to a higher level setup you can start experimenting. Everything matters, and it all matters more the better your system gets.
