At present I am just using one channel of each Sunfire to drive each speaker. It's not bi-amping, but each speaker is receiving the full 300 watts with the power supply which normally drives two channels driving just the one whcih gives it a bit more headroom than if I used just one amp for both channels.
What I will do once I rewire the speakers will be to use one amp vertically for each channel. Basically, I will connect the preamp to each signfire unbalanced with the highs (ribbons) receiving the Current outputs of the left channel and the woofers (through the active crossover) receiving the voltage outputs of the right channel. I then will do the same for the right channel with the other Sunfire.
Traditional biamping would have one unit drive the highs and the other the low signals. By having each amp drive both the high and low signal of one channel you get the same benefits of traditional biamping, but the amp sees both sets of drivers and therefore is more stable. The ribbons get the high current and the woofs get the high voltage. Perfect!
I have an old Audio Control x-over that I'll try unbalanced vertically and a Rane AC23B balanced x-over that I'll try using the Sunfires in a traditional bi-amp configuration and see which is best. I also will try my Ciounterpoint Natural Progression mono blocks on the ribbons and a trusty Sony TA N80ES on the botytom and see if that works better than the dual Sunfires. I also might try the Counterpoints with pone of the Sunfires on the bottom tocover all the bases. Then I'll sell the gear that doesn't make the cut.
