En oppsummering av feil ved objektivistenes klokketro på ABX og blindtesting generelt, og et historisk overblikk over galskapen skrevet av Dr. Raife F. Smith II, professor ved Tulane universitetet i New Orleans.

Seemingly unknown to Drs. Lipshitz and Vanderkooy, much of the basic descriptive vocabulary used by the audio press came directly from peer-reviewed scientific journal papers written by the inventor of stereophonic sound and subsequent researchers in the field. For example, Steinberg and Snow devote considerable discussion to stereophonic depth perception in [9]. T. Somerville in [12] devotes considerable discussion to concert hall and home listening room acoustics. This is the paper in which the term "sound stage" was coined. Somerville discusses reverberation effects (which later came to be called "air" and "ambiance"), sound stage width and depth and "aesthetic presentation". One of the most profound comments made by Somerville was:
"A listener in a concert hall, because of the binaural characteristics of hearing, is able to distinguish between the various sections of the orchestra, and, in particular, he can pick out the solo part. In this, hearing is also assisted by sight." [12]
We now have nearly thirty years of documented experience in the application of blind and A/B/X testing to stereophonic audio systems. The A/B/X test setup arrangements and test results have been consistently absurd and consistently statistically similar to guessing...which is an expected result when the ABX test is used inappropriately and when it is used for low numbers of subjects. One would think that, after all these years of "all amplifiers sound alike", A/B/X and blind listening test proponents would begin to question the validity of their testing methodology. I don't expect this to ever happen because ridiculing audiophiles is so easy and so much fun.
Stereophonic music reproduction is designed according to the principles of sound localization, long term sonic memory of actual musical events, and the reception of tactile sensations from the sound stage. Blind audio testing, which includes visually obscuring all or part of the sound stage, rapid switching of musical selections and off-axis and group seating, impairs the listener's ability to localize sounds (seeing), to internalize and evaluate aural cues (hearing) and to receive correct stereophonic tactile information (touching). Any stereophonic audio system testing methodology which compromises and hinders the processes of human sensory perception will result in consistently inaccurate and often absurd results.
ABX and blind testing proponents say that they want to apply a scientifically rigorous testing methodology to stereophonic audio in order to determine if the claimed differences in audio components actually exist. However, they ignore decades of scientifically and mathematically rigorous subjective listening techniques that were developed by the inventor and subsequent researchers in the field of stereophonic sound.
