Node 2i performance suggestions pls

I'm all for improving sound but I know a fair bit about networking and other than measurable packet loss and/or retransmits (which implies you have general network issues), I see no way that these supposed audio ethernet cables would make a shred of a difference in SQ. At all. Yes, if you doing long runs then better shielding can reduce PL, and if you are doing 10gb then you need Cat6+. But otherwise, what are you guys basing you qualitative statements on? Not trying to start an argument but I have never seen anyone explain how an audiophile grade 'Cat8' cable, or any 'special' ethernet cable is going to somehow magically mean better audio.
