I would like to know where you get your information from.
You call it a scientific fact that replacing stock components in a crossover circuit with components of better tolerances (what is tolerance, anyway?) -- even though they have the same values of resistance, capacitance, and inductance -- results in better performance.
I beg to differ. Perhaps you should explain what you mean by tolerances. Do you mean that the given ratings of the components used in the Axiom XOs are off by a significant margin? Do you really think an expensive and overbuilt capacitor will woo the electrical current into sounding better than one engineered specifically to provide a certain Farad rating?
I understand you're just trying to give us some helpful information, but many of us here like to stick to our healthy sense of skepticism until such "tweaks" can indeed be considered scientific facts.
I'm sure you are familiar with the inescapable psychoacoustic side to audiophilia...
