For a few dollars more there is Nelson Pass's(firstwatt) Do-It-Yourself amp camp. Very nice analog amp. https://diyaudiostore.com/products/amp-camp-amp-kit?variant=...

If you're the kind of person who equates harmonic distortion with "warmth" you're in for a big treat with these Nelson Pass designs. On objective measurements these are just about the worst amps you can buy (or build). We're talking about 2nd harmonics at only -50dB. Warm AF.

Bias current of 1.45A (not ma!) means it'll be pretty warm to the touch too.

The only advantage is simplicity for teaching purposes. Doesn't get simpler than class A.

This is just a quibble, but most switchmode amplifier chips are analog. Granted the term "digital" has been adopted by the audio community for switchmode amplifiers, but it still raises eyebrows.
