In my experience, re-installing (moving), any cables that have already been in your system whether it's sc, ic, or pc, will require that you give the cable time to play. This is true of cables that have gone through break-in. It may take hours and sometimes days before your system sound stabilizes. When cables are disconnected and moved, it alters the sound of a system. I think some folks may jump to erroneous conclusions about the sound of their system when changing out cables because they don't allow the system sound to re-stabilize. This has nothing to do with new cables, which are a different story that involves break-in.
