recommendation cable fix

The manufacturer would be the first choice- if they stand behind their product they should repair it at no charge. 

Yes, the manufacturer should be able to take care of that.  A few years ago, I wanted to change my speaker cables termination, and the first person I thought to call was the manufacturer, and they re-terminated my cable, no problem.    

thanks for the responses.  Paul Garder made these cables and he has stopped producing and has disappeared.   I am looking for someone who could fix this who works as an independent company.

I can no problem , I have rebuilt hiend Loudspeaker Xovers for years 

make loudspeaker purifiers ,jumpers and at 66 keep myself busy and don’t use Crap I use very good quality Cardas Silver solder.,
