There are times where one abandon certain type of sound to favor another. I am one good example, I used to like bright headphones in the 80s, as I age, I prefer a darker signature headhones like the HD650.. and suddenly as times pass, I favor a slightly airy sound signature more like the akg3003i with a slight tizz/sss. I know some user completely change the way they call dark/neutral after listening to certain headphones. What sound so good in the past sound veil now..
That is why I am still stuck here at Headfi cause I was never happy over my current headphone.. I will quite headfi once I gain sound enlightenment
