I do find it very interesting how the "anti ASR" crowd on this forum posts claims and articles "supporting" their perception at a fanatical pace, and when someone posts actual information about how Ethernet works, they can't be bothered.
Another common misconception here is that UpTone and others on this forum is under the impression that the electrical signal is carried through equipment. It is not. It's a point to point going from the transmitter to the receiver. The network receiver reads the electrical signal, but it doesn't actually do anything with that signal, rather creates an aggregate (the Ethernet Frame) of the electrical signal in the digital domain instead the network interface card.
Anyway, keep on doing what you want, but none of you have posted anything that can show a theoretical improvement of sounds quality when you upgrade a cable. And you never will be able to, since it is not possible.
