Why would you even ask such a question? 

Let me guess.

 

You assume that I will answer in the negative and thus validate your audio gospel by illustrating how the heretics here don't even practise what they preach.  Thus, a perfect opportunity is presented for you to resume your offensive against the 'naysayers'.

Well, sorry to disappoint, but whether I have ever used blind testing to select kit is irrelevant to this discussion.  Why?  Because I'm not for a moment saying that people should only use this method to buy new equipment.  What I am saying is that those who spend 5 pages drilling holes in the DBT link and then accusing everyone else of being misguided incompetent meddlers must have something to fear. 

I don't know.  Perhaps they are insecure with their personal choices and are terrified that a DBT would expose their inability to distinguish between cheap and expensive gear. 

Who knows?
