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

.....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 ????   

I would use jumpers made of Cardas Clear Beyond if available

Whilst we're on the subject, jumpers aside, different results may sometimes be obtained from connecting the single wires to the upper or lower set of binding posts.  Some do one upper and one lower.  It's worth a try.  

I just bought a Nordost Norse jumpers I have not try them, I used heimdall 2 on top n clear day on the bottom, for my diapason, they sound amazing, I moved the diapason farther, so the clear day are only 8 ft, I felt the Norse might equal or maybe better, I have to try first to know if indeed are better than clear day, I saw vertical Biwire go on Nordost web site, this might work, will see.

 Nordost norse jumpers are amazingly good, $90 used, I did vertical biwiring, as good as the clear day.they are on my diapason adamantes, the main sp cable is the heimdall....
