Amir's approach still assumes that he is measuring everything that matters in terms of ultimate sound quality
I don't see that, he's measuring the DUT and seeing if it does what the manufacturers claim it does.
Amir talks up the value of unbiased listening tests, but then admits that he is clearly biased and unwilling to go to the trouble of setting up any unbiased listening tests himself.
Why would he set up BDX testing of a component that doesn't do what's claimed? It isn't his place to conduct a DBX but those who claim the component does things the measurements clearly show isn't possible.
