Thanks, Jens......The article is interesting and informative.....But, I
still believe in "power amplifiers".....They get power from the wall to
multiply the audio power output of a signal source......I guess it all
depends on your definition of. "amplify".

The definitions are quite clear if you understand them. You can amplify
voltage, current, power, light etc. The key is simply specifying what you
mean.
