The ANTICABLES Jumpers are simply the award winning ANTICABLES Speaker Wires made in very short lengths. The ANTICABLES Jumpers can be used to replace the bad sounding gold plated brass straps that typically come with bi-wire'able speakers. Brass is simply not a good sounding metal, and when replaced with the solid copper ANTICABLES Jumpers, your system will sound more like real music for very little investment (see Testimonials).
