I've used JPS cables over the years, from basic to SC3 (Aluminata top model = too expensive for me). I find there are two factors, do I like this sound profile or not, and then, how far up the chain can I afford to go. Yes, SC3 sounds better than the original SC, although both are enjoyable in my system. This whole process of cable fitting does make the system sound better, but it is no revolution. Better boxes make more difference than better cables, supports etc.
