First, it's Milind (although your smartphone may have made that "Milan"
) and second, it's complete nonsense. The good Dr strayed out of his field and drifted into audiophile believer territory.
Yes, it's been long debunked:

Yes, well, hydrogen audio totally debunks everything and everybody but Arnie sooner or later.
Seriously, I am not myself qualified to get into Kunchur's actual experiments as to whether they are good, bad or indifferent or whether they prove or disprove a theory about the audible significance of time smearing. The experiments might indeed be imperfect, as the hydrogen audio crowd seems to say. OTOH, the possible hypothesis, Kunchur or not, about the audibility of time smearing lives on. It might have merit, or it might not in spite of Kunchur. The notion has not been disproven, even if Kunchur's experiments are ultimately found wanting, as far as I know. But, if there is something more reliable than hydrogen audio, I would love to know about it.
Therefore, I think, "complete nonsense" may be a rush to judgement. And, I certainly would not rely totally on just comments in any audio forum, even this one, to be the compelling final say on the matter.
