Only you can really say man. I've heard all different opinions between: doesn't matter at all, bi-wiring is best, or bi-amp is best. Different opinions between amateur audiophiles and even dealers. Don't have much to say, except that with bi-wiring I believe you are supposed to gain in performance by separating the respective impedance characteristics of the different drivers. Will you try and post back
If you bi-amp, I would use the same amplifier, or you might have issues with different amounts/qualities of gain and color.
My Polk speakers have dual sets of binding posts (one for highs, one for lows). Currently I have only one set wired, but I was wondering if I would see any benefit if I bi-wired the speakers? I don't have the money to bi-amp (the best solution), but I would like to know if anybody out there has bi-wired their speakers and if the difference was noticeable. Thanks.
