Yes, there is an advantage in bi-amping either vertically or horizontally, but the big advantage would be with actively biamping your speakers, if done right.
I was lucky in that Dan D'Agostino of Krell designed the modifications to my B&W800's as well as the crossover board for his KBX electronic x-over. Altough my speakers have a sensativity rating of 93 dB/watt, the difference was staggering....the biggest improvement that I ever made to my system, bar none.
I would contact Krell and see if they will do the same for your speakers. If they will, save your pennies and buy a KBX, and do the change.
