Hey, as shopping is half the fun, and this is a 'once in a lifetime' sort of opportunity- sure I'll check out the Maggies. I understand their sound is different from electrostats.
I have heard ElectroStats, and in fact, once spent a long evening with an audiophile friend of a friend, who had a major set (don't remember the brand), on those, did come to the conclusion that I didn't all that much care for that sound.
Re the bi-amping, if I end up with Reference Monitors, I won't need to......no woofers. Right now I'm soaking up ideas, and letting you guys help me stir ;-)
