One pair of Inakustik Referenz NF-2404 AIR interconnects in a fantastic condition. The length is 1,5 metre and they have the original RCA interconnects. Retail price is 1.785 euro. Air remains the best insulator for cables. It allows low capacitance and low losses. With the air helix structure of the Referenz NF-2404, they are closer to pure air insulation than ever before. Just as important as the insulation is a homogeneous structure. This means that the conductors and the shielding must maintain precisely defined distances to one another. To meet these requirements, Inakustik have developed a special clip. Strung together in the interior of the cable, several of such clips form the supporting frame that holds the two symmetrically arranged conductors in a helix-shape in the air while keeping the shielding at the exact distance. Obviously, the conductors themselves play a key role, too. For the NF-2404, they are made of 32 high-purity copper wires braided around a PE core. A very thin lacquer coating on the wires prevents the formation of eddy currents inside this Super Speed waveguide. A conductor that can also pass on extremely dynamic signal sequences very quickly and precisely. Check our other listings for more interesting items. Free shipping worldwide!
