That's what is the crux of the matter, Tim - I know that revealing these "subtle" issues in measurements will require creative thinking driven by a desire to get to the truth of the matter - both characteristics that are lacking on this forum, instead settling on mediocre stock measurements to reassure the inmates.
I have faith in what I hear, Tim & it has served me well.
Unfortunately, I neither have the time nor inclination to do these measurements myself but I & others would be willing to try to help anyone who genuinely wants to get to the truth & try to devise measurements which might reveal something of value
We have a perfect example of this earlier with BE's thread on Noise Floor Modulation - he resisted all help & suggestions, instead enforcing his will & control on the supposed "search for a measurement" to reveal noise floor mod. In fact what he was doing was trying to show that NFM (his version of it) was inaudible. And still he has not produced any results.
So, Tim, your claim of " those who are looking for actual audible differences" is far from what is actually the motivation of those here
