Reliable cable repairs?

I have a nice custom silver braid phono cable with cardas connectors. For awhile I was tracking down an unpleasant hum in my turntable setup and eventually isolated the cable as the cause (the noise would come and go as I manipulated the system - originally I thought it was a bad component in the phono stage). More so it is the connection between the cable/ground wire and the DIN female jack... anyone know of a reliable repair service for cables?
