My first thought when reading the title was that someone had started a gofundme for speaker cables.
Definitely have your cables repaired. Look at the terminals on your amp and see if there are any other connection options that might work better than bananas for you. You might even be able to replace the binding posts, but I’m not familiar with your specific amp. You could also check how your cables are run and if you have the right lengths. Your cable shouldn’t work itself out. Before upgrading your cable you might want to figure out what more precisely how this one is failing you (besides working loose and breaking).
