Input Stage The input stage to this amplifier has 3 main parts: a differential BJT pair, a current mirror BJT pair, and a constant current source. Connected to the bases of the BJTs in the differential pair are ... In order for the audio amplifier to function properly, all of the components need to be in good working order. To keep them there ...

Distortion in power amplifiers, Part II: the input stage
https://www.eetimes.com/distortion-in-power-amplifiers-part-ii-the-input-stage/
Power amp design can live with a restricted common-mode range in the input stage that would be unusable in an op-amp, and this gives the designer great scope. Complexity in itself is not a serious disadvantage as the small-signal stages of the typical amplifier are of almost negligible cost compared with mains transformers, heatsinks, etc.
