Many amplifiers and radios get dirtier (when expressed as a ratio of 
desired signal output to distortion product output) when power is 
reduced. Reducing power does not always mean you improved the 
ratio of signal to distortion.

Look at how many tetrode amplifiers are out there, and look at the 
measured IM performance of those amplifiers. Once again it is a 
case of us letting the marketing people tell us how things work, 
and what is "good".
