As I recall, I agreed that their findings were interesting and indicative but that their results were specific to their test conditions and ought not to be generalized. More research is what's called for but hasn't been forthcoming.
You recall incorrectly then. The whole point of CHeever's model is that he used what is known about psychoacoustics and masking as part of his model. More or less a "first principles" approach. It is not specific to a given circuit type or design.
Geddes used what is known about different distortion mechanisms of amplifiers. Coming from a somewhat different direction but still a valid theoretical approach.
