The nature of the market place makes it obvious that true high fidelity isn't what sells. Nobody is standing in the isle of a Best Buy listening for harshness on that $400 pair of Klipsch. Most people LIKE punchy, sterile sound with insanely overblown bass that sounds extremely loud on account of the distortion.
I'm much more concerned with .05% distortion at .5 watts than I am with .005% at 150 watts. For my listening, nothing going on at those levels of power make any difference. Unless you're listening to 82dB/W/M speakers at 20 feet, those levels of power don't make any difference to you either.
