If amplifiers/DAC/CDPs all sound the same assuming certain conditions are met, why is it that those who claim audible differences exist often hear the same things, with the same equipment? Even in the same listening test. Or abroad. What part of the perceptual codec can account for that behaviour?

Just wanted to get some insight as to what might cause this to occur.

Itís plausible, at least. Where there is no scientific reason for a difference, people can still perceive one for whatever reason. Even the slightest association with some other phenomenon, however unconscious it might be, can alter someoneís perceptions if their test is sighted. And when you have people selling effectively identical products at grossly inflated prices, thereís a lot of psychological pressure to justify the latter. An irrelevant association with some other sense is a good way to bolster this, and I would bet that itís been exploited many times.

Of course, weíre overlooking the much simpler possibility that people just think of the reputation of gold as an element and spuriously extrapolate that to an idea that itís better in all respects, even in cases where thereís no physicochemical reason whatsoever.

I remember a few interesting (old) studies about the influence of our brain on what we hear, as reported in Blauert's book Spatial Hearing. JJ/Woodinville, can you comment on the amount of brain correction that can be expected in cases like this (is it limited to lateralization)? Is this similar to getting used to e.g. the sound of a new control room?

If the sensitivity of one ear is artificially increased, as may be accomplished by corrective surgery (Betzold 1890, RŲser 1965), or by partly plugging the opposite ear (Bauer et al. 1966), subjects first report a systematic shift of all auditory events toward the more sensitive ear. After a period of hours, days. or even weeks this shift can recede, and the subjects react once more in a way normal for persons with symmetrical hearing. Clearly a relearning process is at work, since the time of adjustment can be shortened by appropriate training (Bauer et al. 1966).
It is clear from the descriptions of these phenomena that lateralization in connection with interaural sound pressure differences is a time-variant process. Short-term variations can occur in connection with adaptation and fatigue, and long-term variations occur in connection with learning processes.
