That's incorrect. The ABX test is designed--and thus by definition--to detect whether or not one can reliably tell difference. It is not about preference at all. So some DBTs are not about preference. So simply removing "only" doesn't work, and really the whole sentence needs to be reworked to be accurate.
I have never disputed that
fact as I understand what ABX test is designed to do, that is as you stated, "to detect whether or not one can reliably tell difference". I thought I made that clear in my last post but I guess not explicit enough. That said, there is nothing incorrect about my point that ABX test can, or could if that helps, reveal someone's preference, simply because if one can tell a difference, and I mean a real difference, then it is quite possible that one may prefer the sound characteristics/signature of one over the other. Logically speaking, just because something is designed to do one thing, does not mean it cannot do another thing that it is NOT designed to do. The point I tried to make in my post was a point of logic only and nothing more. The logic being, if the test reveals someone's preference, then it must have detected a real difference while if the test detects a difference, it may not reveal that someone has a preference.
With due respect, you seem fixated on what the test is designed to do (and on that point I repeat, I am in agreement from the beginning) and not willing to accept that it can also do something it is not designed to do, or perhaps we got lost in the wording somewhere along the line.
