In their upper-end ICs, Inakustik go to heroic lengths (with small discs with tiny holes in them) to ensure the wires remain in an air dielectric with minimal contact with anything. Black Cat's "wavy" flattened wire takes a less expensive path to achieving something close to 100% air dielectric. Other manufacturers claim an air dielectric but don't post detailed diagrams of how they manage this inside their interconnects.
