I actually have thought about bi-amping in that config. there's an orig. XO-1 crossover (orig. equ. with the MGIIIs) for sale on e-Bay right now that I've been eyeing. I'll probably wait till I get a couple of hundred more hours on the panels as they were just completely rebuilt by Magnepan. Still a tad congested in the middle, but improving nicely by the day.
