The accusation that "burn - in" is more psychological than real only works for the average buyer since he mostly likely purchase a pair of cables and has rely on his memories to tell the difference when he bought it brand new and now.
But this accusation does not work for cable manufacturers because they have a bunch of them lying around - some brand new, some has been used for awhile. So there is no need to recall any "memories" since they can compare side by side brand new cables and old cables. So if they can hear the difference then there is such thing as "psychological".
Cable manufacturers has nothing to gain by this. If you bought a cables and it sucks, you call the manufacturer, they tell you to wait until so and so hours. If after that it still sucks, then they got nothing to gain, because it's still suck.
