The most important consideration in Power Amplifiers is the collector terminal efficiency
of the amplifying component. In practice, among all Amplifier classes, the class A common
emitter Amplifier is the least efficient with the highest collector deficiency which results in
a lot of power and battery consumption, that come with high heat dissipation requirements.
Yet, the class A common emitter Power Amplifier when designed correctly, is the most
widely used to handle large signals and delivers more power gain for outdoor hi-fi musical
systems.
