ABX audiology tests are only useful to identify particular noises and distortion with very short simple signals like tones clicks tone bursts etc.. They are useless with music. Cognitively, as a test for the equipment rather than testing the listener's acuity, it is total nonsense. It is not structured to conform with how musical content is perceived and put to memory. Beyond telling if a piece of audio equipment is grossly incompetent vs. another, the ABX text is an engineer's bias and an incorrect supposition as to the way the hearing and audio processing work. All such evaluations must allow labeled listening - at no time is the listener to listen to a piece under evaluation without knowing (at least generically) what it is. Introduction of a "mystery" sample smears the differences between the particulars of the cognitive tree formed for each item by allocating the perceptual specifics of each unit into the other's cognitive tree.
Beyond grossly incompetent vs. useful, the ABX test is only capable of producing a null result. It is in itself a highly biased test design that disregards entirely how the test equipment (listener) works.
Functionally it is like having a monkey at the keyboard of the PC used to store measurements in the lab, assigning the measurements to files randomly to either item under test. It can not be a useful method to discern performance differences, it is entirely an engineer's conceit...
