I am a newbie in this field. I usually use my LUMIA 1020 as music player but it looks lack of power to driver my earphone DENON AH-C400 compared with connecting to my laptop(Surface Pro). When the song goes to high pitch, I felt the voice fall behind the music. When I connected it to laptop, the voice goes in front of music. So I think the reason is about the power output.
I am now looking at Sony F887, it has good UI, size and design. But I don't know if it has more or equal power output than my laptop.
I know there are some good players like FIIO X3/X5, IBASSO DX50, all of them are powerful enough to drive my little earphone. But I prefer a player has a friendly UI with fair good sound quality. That why I looked at F887.
PS: ZX1 is too much money for me.
Sorry for my poor english.
