What are the differences, if any, between passively bi-AMPING with two 200W amps and bi-WIRING with one 400W amp? For example, would one method be able to handle dynamic peaks better than the other? I kind of get the impression from some people that bi-amping isn't worth the trouble unless you're actively bi-amping. Is this generally true? I can certainly understand the reasoning behind this assertion, but passive bi-amping must provide some improvement, right? It seems that some people don't advocate passive bi-amping, not because it degrades sound quality or anything, but because it's not worth the money over a single amplifier. If I wanted to bi-amp a pair of Paradigm Studio 100's with four channels of an Outlaw 770, for example, should I notice an improvement over using a single [200W] amp channel for each speaker? I've been contemplating an upgrade for many months, and lately my eyes have been set on the Studio 100's and Outlaw amplification. Your thoughts, please.
