What are we objectivists missing?

None of them most of the time learn with their EARS acoustic concrete science in listening experiments...

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.

Share whatever impressions you want but if someone is asking for RELEVANT feedback on a component my or anyones subjective opinion isn't really worth squat.

You seem to completely go past what I wrote. Let me repeat:

Again, I don’t think people are making claims. Instead, they are sharing their impressions. It’s a public forum. Meaning people gather, talk to each other, share what they like and don’t like, sharing their experiences. If you don’t like what people share, ignore them. Let the people who enjoy the discussion with each other be. As easy as that.

You keep focusing on "claims" over and over again. 

Let me break it down for you:

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

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

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"
