It was discovered in the 80s(?) that simple THD measurements are not the simple indicator of a good sound amp.
It was later suggested by some commentators & designers that harmonic distortion types & relative proportions of distortion harmonics, were key to higher-end subjective sound quality.
" quantity measurements are not in themselves meaningful. Quality metrics point to underlying causes that are meaningful, while quantity measurements are too broad to have meaning. "
(Paul McGowan - PS AUDIO)
Below is an example, a tale from PS AUDIO Senior Analog Engineer Darren Myers, refining the design of the Stellar Phono Preamp - the importance of using both using both ears & measurements.
This is one reason, IMO, why not every reputable audio product sounds good - because not every technically good designer, also happens to have 'a good ear' (or trusts his ears)
