Ethernet Cables

Audioquest advertises a series of Ethernet cables they tout as improving sound quality. I have a BDP-1 digital transport that connects to the router via Ethernet cable.

Has anyone had experience with the effect, if any, of alleged higher quality Ethernet cables on sound quality in audio rigs where these cables are required, e.g., with streamers, digital ttansports, etc.? I am skeptical, but I was about power cables too but that disappeared soon enough.
