What are we objectivists missing?

1 - People are free to share their impressions on anything audio in an audio forum

2 - You pick what is relevant to you. Ignore the rest

3 - Something that may not be relevant to you may be relevant to others

I’ll break it down for you.

I don’t care what you and John Doe discuss about subjective impressions. I do ignore it.

I am free to discuss my impressions on anything audio as well.

If the questions asked in an OP are given subjective impressions as answers then I’ll point out to him or her that’s all they are and should be taken with a grain of salt. 

To return to the OPs question. We can't identify if something else needs to be measured based on subjective listening claims. Bias has to be eliminated first.

I don’t care what you and John Doe discuss about subjective impressions. I do ignore it

That’s clear 100% for the "care" part. But, not so sure about the "ignore" part. You seem to reply to all threads on these very "subjective impressions" topics, cables, DACs, you name it. Majority of your 5,000 posts are replies to these threads. Not really ignoring them for some reason, they seem to bother you.

Some other people may, just may, however, be interested on John Doe’s subjective impressions.

Oh... and keep using "claims"

Hear what you hear and love what you like.

  The definition of objectivism is the philosophy or theory that the main objective of the human experience is to pursue personal happiness and respect other humans. An example of objectivism is the philosophy made known by author Ayn Rand

I am happy that we are almost on the same page about that...

My best to you ...

Good experiments use trained and untrained listeners. I agree with  a lot of what you say about audio, not all. To me 90% of what we experience is room/ speaker interaction and how we've tuned them with either passive room threats, EQ or both. As long as your electronic system is competently designed and most is, not specifically made to have a sound signature it's  no more than 10% of it, and yes, that's only my opinion.
