I, like a lot of people got Elco´s best Digital cable on an auction here for a good price. I was so impressed, I bought some of the Silver interconnects. They were good, but I moved up to the Gold, and tried the Ultimate SGI-999s. They are VERY impressive in every way. The build quality is "bulletproof" and sound excellent to me. I am upgrading the STI-2B to true bi-wiring with the Silver on top and CL-200s on the bottom.
Lake513, I would look forward to more comments now that you have used the cables for awhile. I do not claim to have golden ears, and live in Thailand where I cannot audition cables at will. But I use Elco everywhere in my 7.1 system with Apogee Stage speakers and Bel Canto PRePro/ eVo 6. It is sweet!!!
