What are we objectivists missing?

Obviously. Unless you can “prove” it what you hear by either 1) measurements, or 2) third party independent panel certified blind test. Preferably both! Otherwise what you “claim” is null and avoid. You should not post such thing in the internet 😉

A room is like a piano, it is easy to spot a lack with few months of listening experiments though... I never said it was easy for sure.. it must be learned...

People like to qualify 99% of people being deluded like idiots...And they like to put themselves in the 1 % of enlightened spirit. for sure..

This is not a sign of intelligence this labelling fury...

The truth is different, it is more 50 %...

It is more like a Bell or Gauss curve...

Like the I.Q. distribution...

Cretins are not a crowd of 99 %...

More like 50%...

And guess who claim to be in the 1% ?

Myself i claim to be in the good 50%...

I cannot prove it, save by rational post arguments...

It is the difference between what you ACTUALLY hear and what you THINK you hear.

Interesting statement.

What does it mean to actually hear something I don’t think I hear?

My dad has macular degeneration.

If I hold up an envelope to him and say, "What return address do you see, Dad", he will say, "It’s all a blur."

If I then add, "Ok, now what do you think you see, Dad?" He’ll say, "It’s all a blur."

If I then ask him, what’s the difference between what you actually see and what you think you see, he’ll say, "Please stop."

He really sees the blur he thinks he sees. I really see the address that I think I see. If I put it under a microscope, I would really see the pixels I think I see.

There is no independent access to "reality." There are just different components in different complex systems of experience. 

Reality is a word that does no work. 

Subjective claims are null and void for everyone but the one making them. In order to show that the subjective claim has any relevance  beyond that it needs to be verified. This is true for things besides audio as well. I can claim a teapot is orbiting Mars, that I have seen it, but until such time it can be verified this claim is only true for me. This isnt some wild radical notion it's true for all human experiences the idea some ignore it for audio, to claim audio is different is depressing in a way.

The point of blind testing isn't to claim someone is delusional. All humans have biases, the only way to eliminate bias and continue the investigation into why something sounds different is by testing the claim.
