Gosh. He says since there is error correction in networking protocols, it must mean that bits are lost. What he doesn't know is that these networking protocols were designed to transmit data across long distances. It just happens that we also use them when we go short distances in a home. The error retransmission rarely if ever gets used in that scenario. And when it does, it is because of some fault or error condition, not because the Ethernet cable all of a sudden starts to corrupt the bits so much.
I just went out and looked at my Ethernet switch. Here are its stats:
See how there is a sea of zeros for Receive and Transmit despite the high traffic on the ports.
And this is key: we can instrument such things. So if their cable has less errors, all they have to do is run it against a generic cable and report the difference. There is no mystery here.
And oh, the cables above run through our home and are far, far longer than any short run to a DAC or streamer. How is their cable supposed to remedy the long lengths already behind walls???
