Cat 7 Ethernet cables for digital audio that have, among other things, directionality. As an electronic engineer and network engineer I would just like to say why would anyone fall for this crap?
But it's NOT an audio cable, it's a digital network cable.DIRECTIONALITY: All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. Arrows are clearly marked on the connectors to ensure superior sound quality. For best results have the arrow pointing in the direction of the flow of music. For example, NAS to Router, Router to Network Player.
There is no clarity and dynamic contrast in a bit stream.SOLID 100% PERFECT-SURFACE SILVER (PSS) CONDUCTORS: Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion
etc. etc.
