I know that creating a system around a coloration will not work in the face of creating a system around no coloration. Synergies in effect do not work.
I agree that it is a worthwhile goal to build a component that is completly neutral (straight wire with gain) but since we are all using different speakers that in relative terms are all highly colored, couldn't you end up feeding a speaker with a completely uncolored signal and still have sound that is crap.
As long as we have highly colored speakers further complicated by room interactions, it seems we will always be tweaking the system to color it in a way that compensates for speaker and room colorations.
