See how THIS Ethernet cable blows away standard CAT6 cabling.
"The Starlight CAT8 is very different sounding Ethernet cable when compared to my AudioQuest Diamond or Vodka Ethernet cables. The Starlight CAT8 is more extended sounding at the high and low end. This cable has a bit of midrange presence that I liked and didn’t find to be annoying in terms of brightness. The retrieval of high-end detail is outstanding."

Incidentally, for those of you that feel that there are no differences between Ethernet cables, I did some comparisons with a CAT6 Belden Ethernet cable and the Starlight CAT8. The Starlight CAT8 trounced the Belden in terms of sound quality. "
