Though I learned a lot from this discussion, I still don't see why you
would not change the "color" at the input of a "perfect" amp instead of
letting the amp determine the "color". Unless those DSPs compensate for
the distortion in the "non-perfect" amp, those DSPs need a "perfect" amp
as well. Or wrong again?
