Bi-wires links for speakers ?

Just curious, has anyone noted directionality rearing its ugly head for bi-wire links? Are any specialty jumpers marked with arrows?

I'm a noob around here, but, FWLIW, I'm a skeptic.  Very curious, though, whether OP hears a difference from the demo.

Alpha-gt good point, why I rewire my norh 9.0 speaker with siltech, jumpers do have different sound on every system.

Hi
I borrowed the Tellurium Ultra Black bi-wire links cables from my dealer took out
the standard metal strip jumpers which came with the speakers and I couldn't believe my ears : the soundstage suddenly became huge the speakers completely disappeared !
There is a substantial boost in the bass much more massive, deaper and tight.
The little bit brightness I had gone completely all is more natural and calm, 
Further more my system became more detailed and accurate. 
I really don't know what this company is doing with its cables but it's superb.

This links are certainly not going back to
my dealer !
