It is
not to establish rules forbidding or allowing something, it is understanding why some changes are plausible and others just happen in our heads. Then, sharing the results that have a scientific basis and a test "less flawed" than just subjective opinion.
A problematic approach is to try and convince other people that changing cables will change SQ when the only thing to back up those ideas are subjective opinions (that can be easily flawed), denying any scientific proof and having fear over DBT.
When you do a DBT between cables or sources you remove the idea of one being better than other due to price/aesthetics/personal liking/reviews, etc... If a DBT is properly done you arrive to the test zone without knowing anything about the equipment being tested, only that one is A and the other is B, then using you own ear you try to find out which one sounds better to you. However when you have no clue on what sounds better you just guess, and guessing is not knowing. If you do that same test with more people (trained, untrained, good hearing, and even "golden ears"), and no one clearly spots a difference -just guesses- then there is NO difference.
No one has passed a DBT between different cables. They all guessed. Measurements with equipment more precise than our ears show us that there is no audible difference between cables. So how come some people claim there are differences between cables?
Pretty easy, placebo, their test is flawed, trying to justify price, mood, aesthetics, etc...
Conclusion: Cables claiming SQ changes are snake oil.
And we "non believers" know that using cheap or extremely expensive cables will give us the same SQ, then we will be happy listening to our rig, having spent way less money that the "believers", and knowing our hearing capabilities are the same, better or worst than theirs, but we are not leaving anything behind.
