@helomech That is BS. Who trained them to hear that way. I would say fine, if they were a trained musician. Not supposed golden ears. I have been when a few were fooled by low-cost systems when they couldn't see the system playing.
I went through taste training, when I worked at a distillery. I was not as good at others, that is the truth, so unless there is a standard training I don't believe 'Golden Ears' audiophiles. Since I know the rigor that goes into training ONE sense, that is standardized in the industry.
