Hi all you hifi nuts/cr603 owners . i just found an unused power chord which was my free gift from my whf subscription and wondered if it would be a worthwhile tweak/upgrade. i also still have my cheap 79 strand cable hooked up, so my next question is whether its safe/ worthwhile using my silver anniversary bi wire cable with the jumper bars still in place , in single wire mode obviously . would there be much improvement on a system at this level. i have to i am still very impressed with this lil ol box
