AudioQuest Cinnamon RJ45 Ethernet CableRJ E Cinnamon prepared Cat 7 Ethernet cables use solid 1. 25% Silver conductors, which completely eliminate strand interaction, one of the biggest sources of distortion in cables, for clearer, more dynamic and involving sound. Superior conductor metals minimize distortion by having fewer grain boundaries and less impurities (such as oxides) at those boundaries. Solid High Density Polyethylene (PE) insulation helps maintain critical signal pair
