Biamping question ....

OO- if you want to bi-amp- I have a Rane crossover we can make a deal on (the one in my system pics). Dual mono sounds good enough for me!

I've bi-amped the Sunfire cinema speakers, the crs-3s, the AL-3s and my old Klipsch Klf 30s and I have to say that with the ribbons it was a very noticable improvement, not so much with horns though. I imagine that the woofers will benfit most in your situation as the klipsch horns really only need clock radio power to play very loud and clear where the ribbons you can practically plug them into a wall outlet!
