My thought in general (not related to HydrogenAudio)
I think one of the feature of headphones is the difference between them.
The first question we usually ask newbie is what music you listen to and will match the headphones.
All this eventually lead to the finding your sound signature quest.
By doing this we acknowledge that not everyone listen the same and not everyone like the same thing.
Opinion are subjective in nature. And this forum encourage people to have different opinion.
What I see here, is that we can have different flavor of headphones therefore it's acceptable that some people don't like the same thing we do.
But when you try to input false objectiveness. Some people tend to view opinion as fact.
Now
"fact" can be argued about not opinion. When someone take his opinion as fact because he introduce pseudo objectiveness that when thing start to go wrong. He is convince that his
"fact" are true; therefore ready to start a heated argument to defend his
"fact"
Here a very bad analogy I came up with

Arguing opinion is pretty much useless. Like If I said apple pie is much better than sugar pie. Other user can say OK. I like sugar better. End of the discussion. That when you are aware that different people like different stuff.
Now if we introduce opinion as pseudo fact and the goal of an ultimate perfect pie. Apple pie should be baked at 350 F because of the following reason. Then someone come and said No it should be bake at 400 F Then they can get into an argument each with it's own reason. they start to quote "fact" like water content evaporation at which temperature. Dryness whatever. They both try to achieve the mystic perfect pie. But they forget that maybe someone prefer it's pie crispier and the other prefer it moister.
The same thing happen when your goal is this mystic perfect system and you introduce
fact as why this component is better than the other one.
