I talked to a guy from a Denon store today and he said cockily there has never been any driver change in D7200 and everybody is hallucinating or the older headphones just burned in over years... I think he might be misinformed
Because this is the same thing as with perfumes - they tell you there were no reformulations but you clearly smell that the new batch is diluted and watered up, if you know what I mean with this comparison
Politicians also say the gas prices didn't change, but everybody knows they are just BSing you
But I don't know. Haven't heard the older version, I might also be wrong
