You know that upgrading your system's audio cables can improve its performance and sound. The same is true of bi-amp jumper cables. Now you can replace the cheap, gold-plated stamped-brass jumpers included with most bi-ampable speakers with AudioQuest PSC BiWire Jumpers.
These jumpers are made of AudioQuest's high-purity Perfect Surface Copper, for improved signal transfer. And they're silver-plated, to protect the jumpers from sound-degrading oxidation.
