My wife is beautiful, I would hate to be told that I am biased, because that would have a negative implication. It's a polite way (or is it?) of some one telling me I wrong, that she's ugly, and they can provide it to me, by adjusting the lighting or some such thing. And heck, in a certain lighting we can all be made to look ugly. So I like my wife and music with biases, and if you search yourself out, you might just discover that deep down you do to.
Removing bias, outside of controlled lab experiments, well that's not a good idea. It's especially bad to overlay, over everyday listening experiences. Why, well, they cannot be removed from everyday settings such as peoples homes. Therefore the use of an unnatural, unrelated form of audition is illogical, for determining a persons personal preferences, bias and all.
To put it another way, from the consumer standpoint, the best possible means of determining a systems suitability, is almost identical to that of buying clothing, one must try it on. Home based auditions of a complete system, in the intended room, from the intended seating position, is by far and away the best audition
If you wish to temporarily remove ones ever present biases and other influencers, you will only produce a temporary result, one only occurring within that setting. Put one back into the real-world, and they will likely become dissatisfied, with any choices (buying decisions) that were made, from within that unnatural setting. Look, many have, John Atkinson being the most notable, in our circles.
John's opinion is as valid as your own, he finds them deceptive. He has also referred to them as being misleading.
Now the use of the metric that your alluding to (DB ABX), in controlled scientific experiment, is quite another matter altogether. And to be sure there is some very valuable data to be mined.
