actuallyt you can get digital microponones: they measure the displacement of the diaphram by counting fringes on a laser interferometer, so there never is an analogue signal (except the physical movement of the membrane itself).
Damned if I can find a reference to it now... I hope it wasn't an April Fools' Day joke 8-) I think there may be switched-mode audio power amplifiers too, but I doubt they will ever be HiFi compared with high end linear designs.
