Biggest Improvement Speaker Cable Or Interconnects

I recently upgraded from stock power cords and a kimber interconnect and speaker cables to Virtual Dynamics. Their products are a must listen IMO. The greatest improvement came from the power cord, the additional gain from the interconnect and cable was also significant, though I couldn't argue that one was superior. By all means give Virtual Dynamics a try. You can't do better for the money (and maybe not at all)
