I was referring to the ´valid´ point solely. And as far as there are significant deficits regarding this particular parameter exposed by the very loud fraction of the self-declared objectivists, I cannot blame anyone for generally not taking measurements as a proof.
If judgement is subjective, this applies to evolving judgements or predictions from measurements as well. At least in the eyes of those being critical to measurements as a main and only proof, for which there is good reason.
That was my point: Even if Marian’s measurements are accurate in this case and pose enough of evidence for people understanding the technical background, it would not be accepted as proof by others.
I think they are not, as I was not referring to recording or production quality but to the necessary experience with excluding bias in listening tests and getting the results of objective and subjective parameters to a necessary level of congruence. These are exact skills you would acquire at university becoming a pro recording engineer and subsequent decades of experience. It is obvious that some hi-fi or high end pros have these as well, but as it is not a standardized career, it is very difficult for laymen to judge who is right and who is wrong here.
Again, I am not trying to make a point about differences between purely digital sources. Just trying to explain my view why certain positions like Marian’s , which I agree to, are difficult to proof and widely meet misbelief by people siding more with subjectivists.
The part for ´don’t hear´ I tend to agree to.
´Relationship to what we hear´ I disagree with, and that was my point regarding measurements not being taken as a credible proof. Most of popular and regularly executed measurements on hi-fi gear do not allow any prediction on sound quality or character. There is no difference between jitter measurements and THD below a certain level or SINAD. It is all inaudible if not exceeding the audibility threshold previously defined (and that is the only purpose of these measurements).
Looking at the way they are commonly used in hi-fi reviews and discussions drawing invalid conclusions from measurements towards sound quality or sound character, I would clearly disagree. As mentioned, the case for bit-identical digital signals is an exception in which the chain of evidence for the non-existence of differences is complete.
And yes, I see it as a problem that a significant amount of people do not accept such proofs.
