Granted, sighted tests produce false positives, but I would posit that stereo equipment exists to create pleasure in the brain, much like the role of cigarettes. This pleasure can be difficult to capture in the conscious mind, and does not lend itself to discernment, comparing, and "telling." When I smoked, there was no conscious altering of state. I could not say, "I am under the influence of nicotine." I could not say, "This cigarette is better nicotine." The brain just liked nicotine, and cigarettes were a delivery mechanism.
If you removed nicotine from one pack of cigarettes and not the other, and asked me to discern between the two packs, I don't believe I could, but then is the discernment between which cigarette is which really the measure of the related pleasure? If I kept the two packs for a couple of days, I would most likely want more of the pack with nicotine, but I would have a heck of a time telling you why. My failure to discern could lead an observer to conclude that my love of one pack was an illusion.
Why couldn't there be a similar behavior in the pleasure of music delivered through various devices? Why couldn't the brain-level pleasure of music be as difficult to discern as nicotine? "I smoked AmpX and AmpY, and really couldn't 'tell' the difference, but I listen to AmpX three hours a day."
