There will never be any consensus since there's enough of a subjective component to all of this to ensure that even if sufficient testing methodologies are developed and proctored (there's a dearth of proper and detailed study, I believe), some will disagree with these methodologies and others will refuse point blank to accept the results, for reasons of their own.
The solution was to make sure threads stay on topic and to move all discussion about this sort of stuff into its own forum. There is some vocal disapproval of this solution, but I personally think it was the best of several mostly equally bad choices, given the nature of the problem. There are lots of places on the Internet (e.g. Hydrogen Audio) where discussion is highly objective, and you'll see very different attitudes there than you might see on Head-Fi.
