Not true. There's no better than statistical chance, which is between 12-17%; guessing. To the best of my knowledge, that's where everybody ends up after a statistically sufficient number of tests are run. At to a degree of certainty, IIRC, one needs a 70% accuracy rate to be rated statistically significant.
(Anybody is welcome to tighten up my above recollections.)
Next, one needs to take into consideration, how they listen to subject content in real terms. Are they listening in an anechoic chamber or in their living room? Are they listening while alone, or are they listening while having a glass of wine, with loved ones, on the floor with a Yahtzee cup in hand; rattle, rattle, yeah baby, daddy needs those quintuplets. Yes, I remember listening to a $50k, stereo, vinyl system, all by myself, chair in the sweet spot, nobody to distract me while my eyes were closed. Oh, yes, it was gorgeous sound quality. But, our <$8k, 5.2 system sounds gorgeous also.
The funny thing about knowing one's gear, once the sheet goes over their gear, everything immediately disappears and their ability to hear a difference immediately goes South and then the excuses come out. My point, if one needs excuses to defend not telling a differences between a $3k Amp and a $900.00 Amp, then one is not hearing differences as differences are suppose to be easily noticeable as claimed when there's no sheet over the gear.
That's my $0.02 worth regarding personal observations vs personal education efforts on this matter.
