Amir says, "When it comes to non-linear distortions, audiophiles are notoriously poor at hearing those artifacts. It is for this reason that even poor measuring gear is praised as sounding good."
Tsk Tsk, another generalization without supporting data- bad science. Actually, everyone is poor at hearing non-linear distortions because they occur naturally around us and even in our heads, inside our ears to be specific. That is one reason tube amps without negative feedback sound better but SS amps without negative feedback can sound good too but look worse on paper.
I heard arguments once that IM distortion was more critical to a pleasing sound than THD, IM distortion occurs inside our heads too.
Thomas Edison used to have stage shows in the 1900's where he put his new phonograph on stage behind a thin curtain. He had a live opera singer on stage as well. He would have the audience guess if the singing was live or a recording. Sold a lot of phonographs that way.
