Supra Ply 3.4 speakers cables Users?

I am about to give an audition to a set of Supra Ply 3.4 bi-wire speaker cables made in Sweden by a company called Jenving. Had not heard of them before, but have decided to give them a whirl based on a recommendation from as dealer whose previous advise has worked well for me. Anyone else have experience with these? Would be interested in how they sounded with whatever gear on which they've been tried.
