I came on a very interesting theory of acoustic perception in an odd way: My wife met the author, who has a PhD in physics from Harvard. She couldn't follow the theory, but got his business card, which led me to his website:

The first three articles are the key, all with titles beginning with Phase Coherence as a measure of Acoustic Quality. The first paper (on the neural mechanism) gives the basic theory. The articles can be understood reasonably well even if one ignores the equations. My wife reports that Dr Griesinger is very excited by his new theory, but does not yet know if it is correct.
Anyway, I find the theory plausible. And it certainly fits in with people's experience that reproducing the shape of the attack waveform (which requires linear phase response) is acoustically significant.
Dr Griesinger appears to be a bigfoot in Acoustics: LARES - Wikipedia, the free encyclopedia.
