There are many problems with off-the-shelf USB cables including poor quality conductors and dielectrics and insufficient shielding.  Conventional cables induce high amounts of signal jitter and phase noise degrading sonic performance.

The SR-USB-Cable is an exclusive Shunyata Research product that was designed to achieve the ultimate levels of performance without regard to production cost. It starts with our highest grade of ArNi^® wire featuring pure OHNO copper in a VTX™ geometry with fluorocarbon dielectrics.  The power wiring is a completely different type of conductor designed specifically for DC power transfer minimizing any signal transmission interference. Massive silver-plated copper braided shields protect the delicate signals from external RFI/EMI.
