Using speaker cable as jumpers


Hello, everyone
I'm kind of new in this forums, and I guess I will ask something already spoken here a couple of years ago.
I have a pair of Martin Logan's Ascent bought 2nd hand but the jumpers they "bring are 2 pieces of thick copper (pretty much oxidated). I'm wondering if I can/should replace them by Kimber 8TC (which are the cables I'm using with them).

Any suggestions / opinions will be pretty much apreciated.

Thanks

If you plan on keeping the Martin Logans, why not reterminate the Kimber to biwire configuration? Easy to do.
From my experience, silver is the best choice. I have made some comparisons between the original jumper with my speakers, the copper Nordost and 4 pcs of military silver plated jumpers. Only the silver can deliver a detailed treble
"Only the silver can deliver a detailed treble"

When everything else is copper?
Done

Just replaced the old jumpers (that don't even seem to be copper but some other sort of metal (no, not silver, absolutely) and replaced them with the Kimber 8TC and... Helas!!!
More focused bass, midrange and treble more detailed and open.

Anyway, I'm looking forward to try the silver ones.

Thank you all for all the advice.
