In Reply to: RE: Then, what if the measures you take in attempting to reduce distortion just "sound bad" posted by John Marks on June 27, 2014 at 12:19:17
Distortion - is defined as nonlinear signal behavior. The measures whe commonly use in assessing non-linear behavior, THD, IMD, TIM, and a host of other have been chosen for the convenience of measurement - not the perception of its audibility to listeners. Some testers are now considering the weighting of distortion at least toward its perceptibility, or apparent loudness (See Link)
Still we know that some distortions of the signal with some recordings enhance the listeners experience. So do we throw away all distortion assessment?
Certainly not, some distortions are obvious in altering the nature of sound reproduction we wish to achieve. Clipping a key example - where even two similarly rated amplifiers can have very different performance when recovering from clipping.
Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.

If distortion in the playback chain improves the listening experience, something is wrong elsewhere in the playback chain or with the recording or possibly the musicians.

It is more like the device does less damage than others because ALL devices distort. The one that makes the least offensive distortions is the one that is likely to sound the closest to undistorted...which no one has actually ever heard outside of a live, unamplified performance.
