Agree 100%, and good post Gaz.

This forums one of the better ones for that, and that kinda nonsense from people is one of the worst parts of the hobby to me.
Though speaking as a “Subjectivist”, I’d put forward that it works both ways?

I’d never argue with someone over what they are hearing in their own system with their own ears, I’d just have no opinion of my own until I heard the kit for myself.
Not gonna tell anyone they are wrong in what they hear, but as you say, easy to cross the line and put the emphasis on other people must hear the same thing (If their kits up to snuff, ears golden enough etc)
