Put Your Computer-Based Audio System on the Podium with Pure Transmission GT2 USB Cables. 24k Gold-Plated USB 2.0 Connectors And Silver-Plated α (Alpha) OCC Conductors. The GT2 is a beautifully engineered and built USB 2.0 cable for enthusiasts with growing music collections on their computer hard drives looking for high performance sound. Furutech turned its Pure Transmission engineering talents toward creating the highest quality 2.0 USB cable possible. They begin with silver-plated α (Alpha) OCC conductors and a special-grade high-density polyethylene insulation/dielectric. As illustrated below the GT2 features three-layer shielding and specially engineered 24k gold-plated USB 2.0 connectors. As with the more highly specified GT3, the cable wrap includes damping and insulating materials keeping mechanical ringing from affecting the sound. A carefully engineered clamp improves grip and keeps both mechanical and electrical distortion at bay.
