Not a SF owner, but can speak for a recent change to jumpers and their possible merits.
I own a pair of Opera floorstanders (they're at least Italian!)which have biwire connections that I utilized until I upgraded cables(non biwire)
While I actually never listened with the stock jumper plates, I initially used copper foil, and the sound was great. I also experimented with both upper and lower posts, as many insist the UPPER may improve sonics. Couldn't hear a difference.
Purchased jumpers of equal quality to the cable and it did make a sonic improvement, along with connecting cables into top post.
I experienced this, and I'm a HUGE skeptic of audio voodoo-especially cable.
The best way IMO, is to buy a pair(banana plug in your case) and try. You can alway return them if you aren't satisfied.
Good luck.
