Audio power amplifiers are one of the few fields where analog still has the upper hand when high quality is required. In this presentation I will review some of the configurations available and examine their advantages and otherwise. The classical amplifier configuration still remains extremely useful and is capable of very good results in terms of linearity when the design details are handled properly. I hope to show that this can be done easily. Some new findings in minimizing distortion will be presented. I shall also be looking at the issue of noise in power amplifier circuits, and how that too can be reduced as much as possible.
