It depends a lot on the amp. Because the way the x-over is wired the fairly wide overlapping mid frequency range the transformed impedance of the panel dips into sub 3 ohm range. Some tube amps may not like to drive a complex low impedance load. When biamping, not having the two impedances presented by the two trannies in parallel automatically reases the load to a more reasonable 5-6 ohms. This more even load distribution on two separate amps is noticable even with large and capable amps. The other advantage of biamping is the ability to pick your fav amp for the mid and high and another for the bass (of course this will take some level adjusting).
I am using two identical stereo amps to drive the speakers. The difference between single and biamping is not night and day, but it gives some nice reserverves at higher volumes, and everything sounds a bit more rounded out. If i did not already have the amps, i would have looked for a better single amp, which IMHO makes more of a difference.
