Sure, but it'll use less power than a linear amp.
In most office and home applications that's not an issue. Even in mobile
applications like a car, there's plenty of power available.
There's never enough power and cooling available! Car audio is
especially problematic because 12V wiring is expensive and there's no
room for cooling. My Roku Radio uses a Class D amp so the entire
enclosure can be a tuned woofer cabinet without overheating. Small
electronics use Class D so that the audio amp fits on the main PCB
without extra copper layers for cooling.
Home theater also seems to have reached the point where the Class D
electronics are cheaper than the bulk. Half of the new models I saw
this Christmas were Class D.
