In an ABX test, there are two sources. One is ’A’ and the other is ’B.’ They never change. You can go back and forth listening to them as many times as you like. ’A’ will always be ’A’ and ’B’ will always be ’B.’
’X’ is the unknown source for the test subject. It is always either ’A’ or ’B.’ The goal of the test is to determine if the listener - under the test conditions - can reliably determine whether ’X’ is ’A’ or ’B.’ The listener can switch among 'A' 'B' and 'X' as many times as he likes to help him identify whether 'X' is source 'A' or 'B'.
Here’s a link to an ABX comparator that offers more detail.
It amazes me how many people will dismiss the value of an ABX test without even understanding it, to say nothing of not having any actual experience with one.
.... You must have that confused with ABX, where each button push changes but you don’t know to what- A to B, B to A, or no change which is X ...No, that is not at all how an ABX test works.
