bi amp imrpoving?

Psag: Does the megawatt amp allow you to take more control over the system and optimize to your preference?

"Would the use of a single amplifier with megawatt output, used with medium-efficiency speakers, negate any possible additional benefit of biamping?"

In almost every case, yes.

Ngjockey: As I understand it(?), the benefit of biamping is to lower distortion, by providing enough power to each driver, regardless of its impedance. I believe that the goal of a company like Spectron is to build an amp with enough power to do that, obviating the need for biamping.

However, I do wonder if active biamping brings some other benefit. Irvrobinson, what do you think?

Irvrobinson: The reason I ask is because some amplifier designers (Behold for one) are starting to include active crossovers in their amplifiers.

Psag, that's different. I thought you were referring to passive bi-amping. IMO, active bi-amping can be big win, and a single megawatt amp with a passive crossover have to be of *very* high quality to compete. I think we always have to preface questions about bi-amping or multi-amping with whether we are referring to the active or passive case.
