Here we are, all those speaker manufacturers just can't wait to waste money on a second set of seriously overpriced speaker posts and then on a pair of expensive gold plated straps to short the two sets out. Boy they must all be really, really stupid to have done this for years and years.

Every time I have tried good quality speakers wired direct and wired with bi-wire, the bi-wire setup sounded better to me. Use your ears, most stores will lend you a set. If it does nothing, bring them back.
