Denon's $499 Ethernet Cable

Guysmiley777 writes with what looks like a very late (or very, very early) April Fool's joke: "Denon's $499 Ethernet cable 'brings out all the nuances in digital audio reproduction.' Sure, that seems plausible. After all, nuances in digital signals are so subtle. Oh, and 'signal directional markings are provided for optimum signal transfer.'" Considering that $499 will get you a competent laptop these days, I wonder how big the market is for such a thing — then I look at Stereophile magazine's annual list of recommended components. The "view more images" link shows that they take cable porn seriously at Denon.
