Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated copper conductors are excellent for very high-frequency applications, like Ethernet audio. These signals, being such a high frequency travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high quality Ethernet cables.
