Not really.
Someone owning resolving gear is no guarantee of them
(1) judging correctly
(2) not falling for psychoacoustics/placebo
(3) not being prone to human tendency of justifying their expenses that were not due
Besides, if someone isn't open to discussion, and willing to accept that they are human too and that they can err too and that their perceptions might be wrong, and that their observations will be subjected to interrogation/inspection/analysis, they shouldn't go on a public forum posting their opinion.
It is unfortunate that someone will even think just because some people perceive a difference it will become an established truth; and that it will be accepted as discoveries made by a few subjects possibly fallen prey to placebo; who want the rest of the world to believe that tens of thousands of engineers and scientist putting millions of hours and billions of dollars every year in research are idiots. Logic, engineering, science everything is zero. A small bunch of people who have spent money on expensive gear and have put time and effort in things that wouldn't bear fruit are heroes.
