Guys, I noticed that HA-FX850 paired with my android phone (Xperia Z5) sound noticeably worse than from my computer+ Fiio E17 (High gain, volume set to 15 from 60) so i think i might do something to fix that. However, i don't know the requirement of FX850 at all (like how strong an amp need to be to get all juice out?).
Will i be served better with good DAP (like iBasso DX50, Fiio X3II ) -> because it have access to file by itself without having to get signal from phone,
or a dedicate Phone DAC/AMP like Fiio E18 -> because it have better amp?
