The best amplifier is not the one with the shortest signal path or the most expensive capacitors. It is the one that works reliably every time you flip the switch. That is the definition of practical .

Most hobbyists have a 5V phone charger and some old 4-ohm speakers. The PAM8403 circuit (or pre-built module) is foolproof. Practical Audio Amplifier Circuit Projects.pdf

If your search for does not include the LM386, delete it. The LM386 is the 555 timer of the audio world. It requires fewer external parts than a discrete transistor design and runs on 9V batteries. The best amplifier is not the one with
