I have experimented with Ethernet cables a lot. In all price ranges. From consumer grade to Shunyata Omega Ethernet.
First remark: do not expect too much. Ethernet cable is NOT transformative. It will not make a $200 streaming setup sound like a $20,000 setup.
Second, to me, best Ethernet cable, period, is the Synergistic Research Atmosphere X Reference. About $1,000. Cheaper if used or you know a “friendly” dealer.
Third, best no brainer budget Ethernet cable: this Ghent cable from China: https://www.ghentaudio.com/pc/et11.html
