Mahgister and teo_audio,
You put a lot of words down on this topic, but in my opinion they do nothing to advance the debate. To me they are nothing but special pleading sans any justification of said pleading offering no concrete relevance to the discussion. There is a another more apt but colloquial term that I will not use.
It is already accepted that personal preference is real, and absolutely will deviate from whatever measure of accuracy one may choose, and that single components or certain groupings of components can cause these deviations resulting in their being preferred.
The only question that remains is can audiophile detect changes that measurements say do not exist. That is a yes/no question. It will be very difficult to prove no, since negatives are rarely provable. However, the yes only requires showing that someone can do in some experiment that is considered reasonable. Increase the number of people and number of experiment will increase the confidence in the result.
I think almost all here would agree that given the nature of the music creation process before it is in our hands, that objective accuracy is a false notion and even if true, that does not over-rule preference for enjoyment.
If you cannot answer the question of whether audiophiles can truly detect differences that modern test gear says is not there, then all those multitudes of paragraphs are quite meaningless.
