An amplifier is basically a modulated power supply, so the power supply circuitry should get your utmost attention, then only followed by the signal circuitry, not the other way round. I have built a few different versions so I could tell you more about each of them, with some example circuits you could try yourselves. As always, take everything you read with many grains of audiophile salt, me included. The circuits shown on this</description></oembed>
