A nice advantage of class D is low noise if all your ducks are in a row.
GaNFETs have no leads- to connect to them they have solder pads. This allows the designer to minimize stray inductance in the design, which results in lower radiated noise associated with switching (caused by parasitic inductances).
We got our amps so quiet in that regard that most tube amps radiate more noise on the AC line and through the air. This is important since switching noise can mess with digital equipment, tuners and the like.
As anyone who runs horns knows, the noise floor (especially with tubes) is a constant battle. Tube amps, even SETs designed with low gain for horn applications, just are not that quiet.
The Class Ds are obviously lower noise and does not take a back seat on the horns (vs SETs or the like) in terms of sound quality. We've been making OTLs that have gotten many awards and accolades in the high end press for decades now; I think the class Ds sound better in every way.
So win win.
