yesterday I purchased w40 , it sounds great but I still got a question about the source thats better for obtaining the full experience. at the moment i'm using iphone 4 + google play full access subscription, for me its a really good quality audio (320 mp3) but i thought maybe its a good idea to upgrade the source )) additionally to the iphone ive got both cowon c2 & z2 , but the problem is that i have not really found the big difference between the sources. moreover, ive been using several different headphones (a&h xd 53, fidelio x1, klipsch s4, Sennheiser HD 380 Pro, V-moda Crossfade M-80, Audio-Technica ATH-M50, akg k551) and the overall result mainly have not changed .
so, maybe now i've got first headphones where a higher class source is really needed ? ))
as an example , what do you think about iBasso DX50 ? a friend recommended it recently )
and of course im waiting for another suggestions from head-fi professionals !
