For a stage (such as an intermediate, class A stage) where you _do_ want to
verify the output impedance you can either find the resistance _and

bridge (I use a noise bridge) and measure the stage output impedance
directly. Just don't let it break into oscillation on the output of that
poor impedance bridge!

Bull****. In any class of operation, maximum power will be transferred
when the impedances are matched. Period.
