Apparatus and method for switching audio amplification. In an embodiment, an apparatus for switching audio amplification includes an output circuit. The output circuit is coupled to a plurality of different voltage potentials and a first voltage potential, and outputs an output signal to drive a load, wherein each of the different voltage potentials is greater than the first voltage potential. In an exemplary embodiment, a control circuit controls the output circuit to generate the output signal based on one of the different voltage potentials and first voltage potential selectively so as to enable the output signal to switch between any two adjacent corresponding voltage levels of the different voltage potentials and the first voltage potential.
