I remember someone here said that : "If you upgrade from the budget-Level to Mid-Range you will notice a bigger difference in sound than when upgrading from Mid-Range to Audiophile range headphones."
is this true ?
and of course Budget, Mid-Range and Audiophile is defined here :
I have a bunch of Mid-range Headphones : DT990 , SR225i , HD598 , A700x , I am wondering if it is worth getting their audiophile-level versions . will the difference be too huge ?
