A simple test to see if the highs and lows are tied together via using a common ground in the crossover would be to disconnect the shorting strap and then check for continuity between the two ground posts. If there is continuity, bi-wiring would be fine but i would not bi-amp.
Something else to think about when bi-amping is the "time delay" factor of the various amplifiers involved. Due to different "lengths" of the internal circuitry of different amp designs, the signal could come out of one amp slighty ahead or behind the signal from the other amp. This would surely affect the perceived "prat" of the system along with dynamics. Since most manufacturers don't even give this spec, it would strictly be a crapshoot as to whether or not two different amps would work out "cohesively". The only way to get around this "problem" would be to use two identical amplifiers. Sean
