is fiio x3 lacks resolution ? or its analog sound is what giving me that illusion ?! it is very enjoyable ....but i took some time to get used to it and i want to ask adding jds labs C5 to it .....does it increases the sound quality? .. changes the sound signature ? or it will not make any difference !
Lacks resolution? Definitely not the case here.
Perhaps its either the files you're playing through them, or your IEM/HPs?
