Jumper Cables - use the stock or should they be upgraded ?

Wilson Benesch Square 5's and bi-wiring is not required...now back to the question friends

.....the current speakers cables are the Cardas Clear Beyond and a 2.5 meter pair were almost 5 figures......ouch. They took me awhile to pay off. I will check with Cardas as getting another run of those speaker cables in order to bi- wire is out of the price range. I will check with them to see what jumpers they have or would you run / use another company's ????
