I agree with Stehno. Unless you intend to get into active bi-amplification, i would say that better results could be had by going to one high quality amp of higher power capacity. Passively bi-amping may offer a slight benefit, but it is nothing in comparison to going active. Just keep in mind that to REALLY "go active" and achieve optimum results, you would need to bypass the factory crossovers inside the speakers. As such, a call to Martin Logan should probably be the first thing on your list to see what they recommend. Sean
