JD and the others have made some excellent comments, but I would put it a bit differently:
1)There is no well-established technical reason why the wire type used for the short jumper between bi-wire terminals on a speaker will make any difference sonically, assuming the gauge is adequate and good contact is made.
2)Bi-wire vs. single-wire plus jumper can certainly make a difference in many systems, although subjectively the difference may not necessarily be for the better. See the following threads in which people reported an apparent loss in bass when bi-wiring, for which I provided what I believe to be the correct explanation near the end of each thread:

And here is some general background on biwiring and its potential benefits:
