"jumpers" for speaker binding posts?

I own a pair of ProAc Response 2 speakers. The OEM "jumper" wires for these bi-wire capable speakers are quite old and worn. Any recommendations for high quality aftermarket "jumper" cables for these or any bi-wire capable speakers? Thanks in advance!!!
I would suggest going with the cable company of you main speaker cables.
try silver jumpers from Stage III concepts (212-627-5628).price varies with thickness but not overly expensive. i use with wireworld eclipse speaker wire and am happy with the sound.
As a cheap solution try silver solder( just use it off the roll)Get the biggest diameter that will fit. Results are excellent sound at a reasonable price
