I'm no expert, so forgive me if I'm not clear on this, but...My speakers have bi-wire capability. I am using only one amp to power them and the amp does not have outputs for bi-wiring, as some do. There are two sets of speaker outputs, though. Would it work to run "A" set of speaker outputs to one set of posts on the speakers and then run the "B" outputs to the other set of posts? My preamp has two sets of outputs. What if I ran those to two identical amps and then ran the outputs of both amps into the two sets of posts on the speakers? Does any of this increase performance? If I use two amps, is there a crossover available where the amps would be amplifying only the frquencies that go to the set of posts they're wired to?
