@audphile1 Define "highest" quality. I would argue that for this case -as somebody wrote above- a stiff patch cable (which is solid core) is highest quality and making it gold or anything else will NOT increase any relevant performance parameter in order to transfer ethernet signals.
I am both, objectivist but also a believer (litteraly). To find the balance in this hobby matters to me. I would agree that some things cannot be adequately described with our physics, but a lot can. Digital signals are pretty straightforward (and yes, they carry parasitic voltages potentially, but you will NEVER get rid of them with an expensive cable). DROP the cat8 cable and get a Etherregen witch does a lot to clean up the signal.
