bi amp imrpoving?

Thank you, and sorry for railroading this thread.
Hello Simon,
For an amplifier with two outputs on each side (such as the Spectron), is there a theoretical or actual advantage to using one output for the low frequency drivers and the other output for the high frequency drivers?

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

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.
