Lol, you think there aren't?
Whole industries exist to study what makes customer preference tick.
What's that got to do with claims of audibility made here, on a forum devoted to audio science?
Audio science is well aware that people make decisions based on all sorts of 'emotional' reasons -- including reasons that they may not even be aware of.
They'll even pick A over B, when A and B are, by every objective measure, audibly the same.
And then, alas, they'll come here and say something to the effect of : 'Golly, A just sounds so much better than B'!
And ASR will say, 'Are you quite sure it's the sound that leads you to say that?'
Because here we are all shepherds who want to protect lambs that have wandered into our field.
