There was another thread around here discussing Cable Company, maybe it got deleted? It ran for years though. Many people documented their bad experiences, along with many who loved the place.
For me, I say go with a smaller brand that offers some form of demo period or easy returns. Silversmith, Audio Art, Veritas Cables, Triode Wire Lab, Snake River Audio, Audio Sensibility, and many others all make quality cables with low risk to try. The only way you really can judge is in your own system.
