Hello headfier, I'm going to buy sony mdr ex7550 soon. I want to ask you guys opinions, which is a better portable player between dx90 or fiio x5 2nd gen to pair with mdr ex7550? I've read several reviews about this two portable player bit still cant make my mind. My sound preference are good dynamic, airy, good instrument separation and good imaging that when you listen to the music with closed eyes, the instrument played are just like 5 metre from you. Im not into "in your face" type of sound. I'm generally listened to all genre song a bit more to pop. Or you guys can recommend me other portable player to pair with my iem that fit my sound preference. Thank you and sorry for my grammar.
