This is the cable used in our TP Ultra cryo'd interconnects. It is available by the foot to DIY'ers who choose to build his own cables. The TP Ultra features 20 ga. Ultra-Pure .9999 solid copper conductor for positive and 20 ga. stranded for negative. We chose a flexible low absorption "DAS" PE dielectric for its naturalness and musicality. Shielding used is of .9999 pure copper and separated from the signal carrying wires by a thick layer of PE to prevent signal interaction and preserve signal integrity. The TP Ultra interconnect is designed to deliver exceptional detail and precise imaging. It is neutral and consistent throughout the length of the cable. The performance of the TP Ultra interconnect will be a delight for music lovers. This cable is the Cryogenically treated version. $4.00 per foot.
