Do you think waiting for a higher end DAP is not worth? :/
I like the Fiio X3, but I don't think is much of an upgrade against the X1...
When i decided to buy the X1 I was debating between the X3 and X1 and it was not clear the X3 being and upgrade, however, it may sound a lot better coupled with the he400is
I don't know if the newer gear is better, the newer X3ii does not sound as nice as the older X3 but the UI is so much better. If I were to get a higher end DAP I would go for something Android based with a touch screen like the X7 or DX-P1 or maybe AK120, or QP1R but since I rarely need this level of quality with portable gear I've never really looked into them.
