Then the likes of Matti Otala started publishing papers. I suspect he went a bit overboard, but he had uncovered a legitimate concern and an area which wasn't being properly handled.
Every now and then someone brings out an amplifier where it looks like nobody checked the crossover distortion. Maybe it was blind cost-paring. How to do it well has been documented well (Self)
