In my experience, bi-wiring is always an improvement. I do somewhat agree with the opinion held by some individuals that high quality single speaker cables will often outperform modest quality bi-wire speaker cables. However, if everything is equal then bi-wiring is always better.
I have no direct experience with Coincident speakers or cables, but on my old Spendors, 'shotgun' style bi-wire cables made a significant improvement over several types of single speaker cables.
