Not only ULF, and not only the usual "dead" audiophile drivers, and not just raw amp power. My experience suggests that direct radiator drivers from 10" diameter and under claimed "100 dB efficiency" (and - especially - in multiples) can benefit from an amp of this sort. Guesses as to why abound, but it seems to have to do with the amp's ability to interface with the motor(s), including reactive loading and the reciprocal "weight" of the drivers' physical and electrical "mass". Sure, there are other strategies for amp/driver interaction, but amps like this one can be implemented to better effect than typical salon/audiophile installations suggest.
Setting aside cost/benefit considerations, and setting aside the norms in terms of sound yields, there is nothing wrong and lots right with working power, per se, as a concept. And who knows, these might just make someone's Alexandrias sound their best...
