I think the nonbelievers are overlooking the circumstantial evidence of the vast numbers of listeners that can tell a difference and the cable manufacturers that spend untold thousands of careful listening hours to perfect their products while listening to burn in.. In a court of law would this prove burn in is not a fallacy but true? Known science would be taken into consideration.

>>>>>I hate to judge too quickly but my sense is that naysayers aren’t really interested in evidence. Whoa! Did I just say that?! 😳

The opinion of a vast number of listeners , pro or con, doesn't rise to the level of circumstantial evidence.  It seems to be on audio forums and popular TV shows  but not in court. Opinions are not admisible as circumstantial evidence in court unless they are given by credtialed experts. This notion

"the vast numbers of listeners that can tell a difference and the cable manufacturers that spend untold thousands of careful listening hours"

is circumstantial evidence in  court  is wrong,  it's opinion and would not be admissible. 

I’m pretty sure opinion is admissible in court. Some opinion is more “expert” than others, that’s all. That’s why, in the case of judges or lawyers’ opinions, they’re called legal opinions. Anyway, that’s my opinion. 😳

The question was
"In a court of law would this prove burn in is not a fallacy but true?"
The answer is no it's not even circumstantial evidence.
