To be fair, I believe the Sound Science forum was created so that there could a space dedicated to the discussion of such things as DBT. As I recall, prior to the Sound Science forum, there was no place to discuss DBT on HF because of the outright ban. But, yes, discussion of DBT and the like is not generally embraced here.
Regardless, we, the head-fi community as a whole, are to blame for the deluge of claims about unicorns and pixie dust that transform mediocre systems into transcendent rigs. A potent mixture of insecurity, laziness, and ignorance seems to have created a fair amount of group think about cables and many other things headphone-related. Check out the review section, every single piece of gear gets 5 stars. Why is that? There's plenty of gear out there that sucks. But we have allowed this to happen. For every person who just wants to chat about some gear--both positive and negative--it now seems there are 3-5 who want to shove an 18 AWG interconnect down their throat. Head-Fi is not controlled by some secret group who decides what is and what is not discussed. We, for the most part, determine what gets discussed here. And DBT-ban or not, it seems clear that the majority of members want to engage in claims about things that can never be refuted and to approach headphone stuff with no more than the most superficial amount of thought or introspection.
So until such time as sufficient numbers of head-fiers have had enough of such talk, this is the way it will be.
