To add to the above - compared to headphones, which is usually around 16~300 ohm, an headphone amp generally has at least 5000 ohm input impedance and can go up to 10~20k ohm or more. That will push the corner frequency to a very low point, usually well under 20Hz and thus curing any roll-off issue.

For example, with a 220uF caps and a 16ohm headphone, corner freq. (-3dB) is calculated at 45Hz. But with an amp of 5k ohm input impedance, it is 0.14Hz, which is as flat as you can hear,

Right, thanks.

So as I knew that a higher impedance headphone will cause less roll-off the amps input impedance is so high it completely resolves the issue.

Thanks for stopping by!

How about Fiio X1 + Topping NX1?

Sure, will work well.

^ ignore that post!

Well remember, the budget is dap AND an amp. But the xDuoo X3 is something I will keep in the back of my mind.

 
by way of encouragement; its a cool set up. feels great too

Thank you guys so much for the suggestions and help, and because the loves for the C3, even though its UI may not be the best, I have a strange feeling I will enjoy it, besides whats the worst that could happen?
Well, my first portable setup, Colorfly C3 + Topping NX1 with Sony XB90EX. TO AMAZON!

I will post some pictures once they arrive and will update everyone on my opinion of them.

All good purchases. I'll just add a little note here, I have the C3 and the NX1 and while I love them both I almost never pair them because I find the result less pleasing than the C3 on it's own.
 
I'm driving 32ohm ear buds (VE monks) and the C3 provides plenty of volume when driving these so the NX1 doesn't add anything except for a rotary volume control.
 
The NX1 does, however, lead to a very slight reduction in sound-stage and takes a bit of sparkle off of the highs in comparison to having the C3 directly driving the Monks. It's a subtle difference but I do hear it, and I prefer the sound when direct driving.
 
I've never heard the Sony XB90EX, so I don't know how much power they need to be driven well, but unless they're high-ohm monsters you might well find that the C3 is all you need. Of course, if you're also planning to drive high impedance full-size phones then then NX1 will come into it's own.
 
I do still get use out of my NX1, it's part of my back-up rig (iPod 1G, line out to NX1, driving KZ ATE IEMs), but the sound still isn't quite as sweet as the C3

I need the NX1 to drive my Havi's although may try the Vsonics without it.

XB90EX's are bass heavy monsters, and while they sound amazing, I have been told using an amp helps it out a lot.

Fair enough, I'll be very interested to read your impressions of the combo, if you'd care tell us

Of course I will share my experiences, isn't that a component of being an audiophile?

Yes. That, and a propensity to worry, needlessly, about how much oxygen is in your cables :-D

ive only had mine a month so cant really comment. also my X2's seem totally fine after nearly a years usage. the sound from the C3 is lovely tho, although it needs an amp.
 
my only issue with it is that it doesnt remember where you left off after a switch off period. grrrrrrr.

 
Nobody else has ever had that issue! 
 

So here is my C3 situation...I don't know if I should get it! XD
I plan to combo my xb90ex's with the C3 and a E11k, but from what I have heard, the UI just can't compare to the X1...but I found the C3 for only $65 USD, which is great for my wallet.

 
I'd recommend the Xeulin ihifi 770C (found on massdrop occasionally for < $100). It has wonderful SQ (and auto shutoff and auto resume!). The UI was pretty basic, and there were issues with playing highly compressed flac files. But it is now rockboxed, so the UI is rockbox-good and I presume the issues with compressed flac files is fixed as well.
 
Edit: I see that you may have already found your solution. If so, good luck!

mine doesnt resume playing where i left it after switch off ... everyone elses does?!
 
it just restarts at the 'internal' 'TF card' menu.

I don't use the C3 anymore but I can't bring myself to sell it.
