The center pin is typically referred to as the "hot" side of the circuit while the outer "ring" or "clamp" section is "ground". As such, the signal passes through both parts of the connector. While the cables might not look like new anymore, i sincerely doubt that the performance has been altered one iota so long as they make a solid connection to the components' RCA jacks. Relax and enjoy. Next time, DON'T eat your Wheaties before trying to "crimp" or "tighten" : ) Sean
