Need New Speaker Cables to Replace my Nordost SPM's


Any thoughts on Cables.  I currently have Nordost SPM's That I purchased new years ago.  Using B&W N802 speakers.  So I need Bi-Wired.

Budget is 3K Used.

I found that a single run with the "Nordost" diagnal jumper method provided best results. Shotgun may be even better but expensive, I was using Cardas at the time.
Jperry is right just move up to their next level of Nordost.i can suggest clear cables, I used them with my heimdall 2 Biwire for my Diapason Adamantes, result is amazingly good...the clear day is on bass the H2 on the high...they match well....
I used the jumper of Nordost the $160. I prefer the clear day jumper.The clear day speaker cables is way better than any of the jumper above...
