yeah but in the real world if one can get one's hands on a $2,000 player and a $150 player and if one thinks the $2,000 player sounds better, what should one do? if the person wants to enjoy his/her sound, it would seem to be unwise to tell this person to buy the cheaper player simply because scientists said there is no difference. those experiments have nothing to do with said person's bias. those biases are indeed real. and the normal person isn't likely to put each player into a perfectly controlled environment that will prove to them they are the same. so, in the real world, the average person is always left to their biases and what/which devices make them feel better. always.
