Keith, would you accept that what you call "sterile" sound is distorted sound, in the sense that if you were measuring for distortion using an appropriately sensitive technique that in fact the replay was "wrong", there was audible distortion being contributed by the playback mechanism, being added to the end sound?If people deny that sterile sound even exists, and instead focus on the measured performance of a system ... the resulting sound will be sterile. I have heard a dozen examples of this phenomenon.
