Truth in advertising here ( while listening to a tube amp here )
is that most sales are towards a amp with the most power out into
a resisive dummy load.

1) Real speakers are inductive not a 200 watt 4 ohm resistor.
2) Lots of feedback is used to keep a transistor amp linear.
3) Sine waves in a lab is different from real music.
4) People buy amps to be loud for loud rock music.
