I'll also chime in that I've found John's KCI Silkworm + interconnects to be the best in my system. For reference I've tried quite a few other big name cables, such as Cardas Golden Cross, Purist Audio Design, and others. Still have and use a pair of Cardas Golden Presence which I also like a lot, but my preference for my 'best' source is the KCI Silkworm+!
