I stopped in to visit the dealer from whom I purchased my components from 2 years ago (Sim Audio integraded amp & cd player, JM Focal Electra 926 speakers). He advised me to upgrade my interconnect cables. I have Synergistic Research Alpha Sterling...he suggested I upgrade to SR Kaleidescope Phase 1. Does it really make that much of a difference, and is the cost worth it? Help, anyone? Thanks!
