Biamping question.

i have vtl mb125 mono blocks, they are great amps, i was thionking about biamping, i am looking at a pair of vtl deluxe 120 to go with the mb125.. any ideas on how this combo might work? i have ascendo c7 speakers, sound amazing and i am thinking that biamping with close matching power might kick it up a few notches. Any input is greatly appreciated
thanks
