Switching amps are much like swtiching voltage regulators, except
that the signal being amplified serves as the reference voltage.
Some care has to be taken to get sufficient bandwidth for audio
applications.  Most uses are for motor control.  Somebody once
mentioned that a football stadium used a several KW switching amp
in the PA system.
