Right on Jon, my old hearing is clearly impaired *grins!*
Actually, I examine amps one brand at a time, and one model at a time.
Currently, my favorite uber amps sound comes from Acoustic Research, Brmester, Solution, and yes... Rowland. Any of these brands have some machines that make enchanting music to my ears.
Class D has the same potential for good and bad sound as any other base topology... It all depends on componentry, goals, design, and implementation. All other things being equal, The common advantage of Class D over other topologies remains energy efficiency, hence minimum cost of operation.
Is class D inherently great? Heck no! I have heard certain current class D amps sounding positively acrid... Best used in attics.... They chase Roaches and other critters away for pennies a day. But so do some much vaunted class A/B devices, and more than a handful of tube amps... At a higher operating cost, that is *grins!*
Bottom line... Generalizations are a slippery business.
