I hate to say it, but he's an idiot, and makes no sense.
Early digital being the "most pure"? Seriously? Bolose 901's not going below 250hz or "3 or 4 k"? I don't like the 901 but I know they have more frequency response than that. 96k "not being in the music"? 96k is the SAMPLING RATE, which would make a 48khz maximum frequency response limit, which some acoustic instruments DO have resonances up there. Might not be there much, but it could be.
He has no comprehension of what they're talking about, and while his ears might not be lying, the terminology is beyond wrong.
I do agree with his views on recording technique, bleed, and leakage, though.
