Overcoming the Perception Problem

Abstract: A positive DBT result establishes reliably that two outcomes or entities differ. A negative means - equally - either a) the two objects are identical, or b) that the method doesn't permit resolution of their differences. No, you are wrong at the second part. You don't set up DBT of lossy audio encoders on supertweeters, with FR form 35 kHz to 80 kHz. That method is not going to give anything useful. It's idiotic. Do you really think that peope can't make valid DBT audio tests? It has been done in the past numerous times. If you set up test correctly, as expected, there will be only "yes, I can definitely hear the difference between A and B", and "no, I can't hear shit". It doesn't matter if the difference in reality is so subtle you can't hear it (lossless vs high bitrate lossy), because the only thing you are testing is if you can hear that difference, and the results are YES and NO. There is no MAYBE UNDER CERTAIN CIRCUMSTANCES, because you then recreate those circumstances and repeat the test. As many times you want, as long as you need. The trouble is when you realize that you have all that 24/96 music, with fancy expensive amp and loudspeakers hand made from Siberian wood which grew in Tunguska at the crater (not to forget hand-made speaker drivers), and you can't hear the difference from 128 kbit aac file and that high bitrate lossless file. Then the imagination kicks in. And you, sir, are the product of that mentality, which is contagious.
