I'm sure I'll get flamed, but...the file delivered to your streamer is bit checked and once the streamer has what it needs it plays whatever it was sent, no matter what cable delivered it.
Cables matter, I am not a cable naysayer, but if you can stream 4K video successfully over wifi, then an audio file is a piece of cake, so a decent quality ethernet cable (I use Blue Jeans) is all you need.
Power supplies, downstream cables, the DAC etc. all matter - more.
