What is "Switch-Mode Amplifier"? - inSync
https://www.sweetwater.com/insync/switch-mode-amplifier/
A Class-D Amplifier, or “switch-mode” amplifier, consists of three stages: the input switching stage, the power amplification stage, and the output filter stage. The signal to be amplified is converted into amplitude pulses, so the active devices switch rapidly back and forth between a fully conductive and nonconductive state.

A class D amplifier is a switching power supply. Those are more common these days and can have quite good specs. Audiophools may wrinkle their noses when they are told a amplifier is class D or has a switching power supply inside, but such a thing is harder to detect in a proper double blind test. In the audio world, it can be difficult to separate the science and …
