Wireworld has invested in decades of research, testing and development to create digital audio cables that overcome audible losses and provide substantial upgrades in resolution, image focus and dynamic contrast. The patented DNA Helix design and advanced COMPOSILEX 5 insulation in these Series 10 cables were developed through listening tests that compared prototype cables to virtually loss-free direct connections. This science-based process resulted in technical improvements that minimize sonic artifacts and masking effects. 75-Ohm digital audio cables are terminated with patented ultra-quiet silver-clad OFC RCA plugs.
