SPEAKERS JUMPER CABLES

Jumpers are a step up from the manufacturer supplied jumpers. Another step up would be to biwire from the amp. My amp has 2 pairs of posts per channel and I Tri-wire my usher’s from the same cable manufacturer. 

I disagree with the "bad jumpers from manufacturers" statements...Alan Yun from Silverline said his jumpers, which came with my Prelude speakers, were excellent, and he also said Preludes sound better when not bi-wired...I made some jumpers from some premium (same stuff as the solid core speaker wire being used) cable anyway and yeah...he was right. I bi-wire my current speakers so it's mostly a moot thing, but I did try a single wired jumper swap with 3 options (two "premium" solid core jumpers and the stock brass ones) and the stock sounded better, but not as good as bi-wired (Klipsch Heresy IIIs).

true, each speaker is different and supplied jumpers range from terrific to throw in junk...My Dali speakers came with jumpers made from the wire used internally...

I love my Dali Epicon 6s.  Love them 

Same for my Epicon 8. The jumpers I referred to were for my MS4
