The Diamond Series SS Jumpers are based off our Diamond Series XSR Reference Speaker Cable. Made with pure Oxygen-Free 10awg pure copper construction and designed to be used with any speaker regardless of internal wiring or x-over makeup. The SS Jumper is ideal for those who want seamless, precise, full-bodied tonality without losing any positive performance you already enjoy with your speakers or speaker cable. Fast, accurate and lends increased sound stage width and depth and can increase imaging as well as midrange clarity. An inexpensive upgrade that suits even the most expensive set ups.
