I found reading this article from last fall by Roberty Harley in the Absolute Sound about amplifier types useful & informative:

http://www.theabsolutesound.com/articles/a-survey-of-amplifier-types-tas-217-1/

I recommended to anyone whether knowledgeable and looking for a refresher, or someone newer to this hobby looking to understand the various amplifier types, their design, and relative merits.

Look interesting, but the last paragraph makes me wonder if the rest is worth reading. I'd be interested in seeing plots with actual distortion spectra.
