Choosing an amplifier
A power rating means most when stated in full: watts per channel at 8 ohms, across 20 to 20,000 Hz, at a stated distortion, with all channels driven. Polk Audio warns that a figure at 1 kHz with one channel driven overstates real power.
Class D amplifiers waste much less power as heat than Class A, AB or B designs, Analog Devices says, so they run cooler.
