Bull****.

No, it's true.

There are cases when the notion that non-blind tests are "inherently
unreliable" just doesn't wash. I'm sure that, if "Callas" was fed a
spoonful of ****e, and a spoonful of sugar, s/he/it would be able to
establish which is the ****e and which s the sugar, and could do so
regardless of whether or not they were blindfolded. Indeed, even if
one were to conduct a hundred such tests 'eyes-on' and a hundred
blind, I bet the result would be consistent and reliable.

That's not the same as comparing reasonably good DACs.

Do try to make your comments relevant to the topic described in the title
