Not crazy. But you will typically need a means of adjusting gain as between the separate amps to make them equal. Usually done at the active crossover stage.
Biamping with very different amps
I'm considering biamping the HF/MF units of KEF Reference 107/2s with a pair of Cary CAD 572SE monoblocks and the LF with a pair of Parasound JC 1 monoblocks. Does that seem a crazy idea?
