With due respect, just for balance of message, an actual computer network engineer will tell you that any adequately designed cat 5e or above cable, within spec., will deliver the same sound.
Secondarily, be careful with Cat 8 and such - for reasons having nothing to do with data transmission for audio, their shielded design can actually be counter to the desire to eliminate the supposed "electrical noise" that networks supposedly carry. I’m not saying I believe in that, but the point is, you don’t just buy a "higher number" cable and think you’ve got something.
Any network tweaking, should you lean in that direction, should be done well after you have optimized your DAC (more critical) and streamer (less so) and digital source material (very much more so than anything else!).
I’m not an ASR fanatic by any means. But you absolutely cannot apply analog audio logic to digital anything. It’s important to understand how these things work well enough to focus on the things you can affect. Network switches, cables, regenerators, eh, if you don’t hear dropouts, the data is getting there.
