I'm actually unqualified to participate in this discussion, but I have been reading their discussions off and on, and wanted to point out that their stance is quite different from what you are saying.
To quote from their FAQ:
"We're an objectivist audio community here. We don't necesarily believe that everything can be measured (psychoacoustic codecs prevent that anyway), but we do believe that subective opinions should be backed up by rigorous tests, intended to remove all possible bias from human subjective judgements and opinions."

FAQ point 8:
"Hydrogenaudio is supposed to be an objectively minded community that relies on double-blind testing and relevant methods of comparison in discussion about sound quality. The usual "audiophile" speak of non-audio related terms which are completely subjective and open to redefinition on a whim, are useless for any sort of progression in discussion.
This rule is the very core of Hydrogenaudio, so it is very important that you follow it. "

Considering their strict stance on ABX double blind testing as the only measure (while ignoring technical measurements and ignoring other forms of subjective measurements), I find their discussions quite valuable to read.
Edit: Just wanted to add that I am not trying to promote (or discredit) hydrogenaudio in this post. I don't have the depth of knowledge to make such statements. Just wanted to clarify what the forum stands for, that's all.
