Amir keeps on posting that graph on trained vs. untrained listeners. What is a trained listener...someone who has passed the Harmon test, and who now believes he/she can tell what a musical sound sounds like, better than the ’unwashed’ masses.
Harman offers that training tool for anyone who cares to use it. I highly encourage you to at least try it before opining this way. Until then, let me explain what it is.
You are presented with music that has an EQ applied to it. You get to tell what that filtering is. It starts easy with very wide band filters but progressively gets narrower and hence more difficult. With practice, your hearing acuity for tonal errors improves and with it, reliable ability to determine colorations in speakers.
Importantly, the test has nothing to do with "harman" or any speaker or technology. It is a pure test of whether you can tell what coloration a speaker imparts -- precisely what we want to determine in such tests.
FYI, after just limited amount of training using above software, I attended a gathering at Harman of top acousticians. Dr. Olive took us to their listening room and played the training test. Everyone got to level 2 or 3 but from there, they became silent as they could no longer detect the differences. I went to level 5 and 6 to shock of everyone there. Before you think I am gloating, Dr. Olive sailed way past me with incredible ease! Here is a picture of him at the meeting doing this:

You can faintly see the image of the training software on the screen.
Some things need proper training. You can't be self-thought in everything especially when you have not passed any test to determine what you really know. The reviewers got tested. They didn't know what they were doing.
