Class D are much more efficient so more bang for your buck. Class AB amplifiers may introduce some crossover distortion but they get closer to the ideal of Class A for most of its operating regime. So where a normal Class AB amplifier operates at 60 Hz in North America and 50Hz in Europe and most of Asia a Class D might operate at frequencies as high as 500000 cycles.
In short it is making a larger identical signal. Class D Amplifiers have long been termed un-musical and as a result ignored for years. I currently have a pair of Schiit gasp Vidars driving a pair of Magnepan 17i speakers.
