Very interesting thread, why not indeed believe the possibility of Ethernet cables making some difference as do all the rest of the cables in your system?
Not sure how much difference but I feel there must be some to possibly be heard.
From the start I have been using cat 7 shielded cables that we use for our industrial electronics connections as these have to be able to reliably communicate in extreme high voltage and high current enviroments.
I ran direct hard wire from my main router to a 4 port switch in my music room and patch cables from there to my vault2, Oppo and Samsung Smart tv.
Do these work better than say cat5 unshielded? No idea as these are all I have ever used right from the start tbh, but we have no issues in our industrial usage which are online and active 24/7/365.
