BTW to let you know the Ethernet sounds way better than any SPDIF cable period. TWL/PIA Ethernet triumphs the Wireworld [$210] I would like to try an all silver conductor one, hint, hint.
SPDIF I tried are TWL/PIA, Mad Scientist, VooDoo, Nordost, JPS Labs and generic both BNC and coaxial. No RJ45 no modular upgradable DACs your old digital is not up to snuff any longer.
