i would recommend dx90 for the multipurpose function embedded,it can line out, 3 gain levels, coaxial out, dac on pc, support micro sd and usb otg, can use rockbox or custom tuned official firmware, with so much feature on a dual dac device,what's not to like? it's like a general problem solver
besides that, there are official staff of ibasso specifically dealing with dx90 issues on headfi forum, that's almost live support as per say
One of my concerns is also that the DX90 would be too good for the earphones that i have now and I would be essentially wasting it..

Go for the DX90, or if you can wait, FiiO X5ii, which will be launched soon.
Audition both of them if you can, and choose the one that you like most.
I'm not in a big hurry to get a dap. So yes thanks for suggesting this, i would wait and try both then decide!

I'd say go for the X1 (don't need to get another DAC) and invest more on a better IEM.
You'd hear more difference on a X1 + better IEM compared to a DX90 + SE215/Goldring
What you say actually does make sense. Is the X1 considered a step up from a smartphone though?

X1 only has line out and phone out, no digital out. Can't connect with external dac ya.

Thanks for letting me know! I was confused with the picture of FiiO X1 DAP + E11K amplifier and thought the E11K a DAC.
So thank you everyone. Sounds like either the Fiio X1 and the iBasso dx90 both have their pros. I will find a day to try them both (and maybe even the Fiio x5ii) before finally making a decision.
