As one member here said, "Bi-wiring may or may not make a difference, and if it makes a difference, it may or may not be better." Some speakers have actually been designed for Bi-wiring, but for the majority, it's just "audio fashion." Bi-amping done properly means you would need to bypass the speaker's internal crossover and use an external crossover. Keep it simple with one quality amp and a single run of speaker cable, you'll have less headaches and more enjoyment.

I already have bi-wire speaker cables. If nothing else, it's less resistance. But I do hear a difference. It's subtle.
I noticed a much bigger difference when I wired my speakers in parallel (ch A to High Fr and ch B to Low Fr) on each speaker. I did this with my cheap Sony 2 channel amp (100W per channel @ 8ohm) and ran A+B at moderate volume levels for a month or so before someone told me I was crazy to do that and so I stopped and went back to bi-wire. Its a cheap amp though and it sounded WAY better so I'm thinking about doing it again! There was more separation, and energy, especially through the midrange. I don't know the internals of this specific amp but it made everything sound better.
This is why I want to bi-amp these speakers if I'm going to spend money on an upgrade...
