Nice to meet you 1

Haureux owner of a very good Harman Kardon HD 970 CD player (Diapason d'Or in 2005), I was reading the CD to start slow, painful and burning MP3.
So I was trying to replace a very good DAC and affordable, to interface my laptop with my chénifi and so easily scan and manage my CD collection.
I saw that X3 could do all this by himself, in 24/192, but I wish he can connect more to my smartphone or tablet, to enjoy the large screens and apps ...
Stroke of luck, last November, Mr. Fiio update its firmware and makes the USB DAC object. And asynchronous siouplait.!

Buy pronto. Here are my impressions:

* Beautiful object, well finished, while very compact metal but a bit "heavy", very reassuring short, so German quality. Not particularly sexy, but endearing.
* The doc in French (including firmware update) is clear and detailed.
* The control buttons fall well under the fingers and use is intuitive (and I am a fifties)
* I will not detail the interface, which is basic as expected, no frills but efficient and ergonomic.

And the sound?
The headphone output is remarkable. I never heard anything like it. This is better than a CD on my headphone output (excellent) amp: the same tonal balance, with a little more dynamics, definition, respect for stamps, aeration, sound plans.
NB: since I compared by plugging the Fiio a super dedicated headphone amp. Well, it's still a little bit better, but it would make a (big) and more device and its power supply to plug in, and quite zeuros to add.

Now the only DAC:
That's good, nothing to say. Very clean. Impec.
Note that this is not better (but good) as my Harman Kardon CD player - which is separable, with SPDIF / Optical inputs.
Actually it is kif kif. But given the space, cost, and potential, there's no picture ;-)

Now a bunch of pleasant details:
- Switching on / off 3 sec (those with a smartphone, tablet or PC worst appreciate)
- Emphasis manageable before (but I would like a maximum of 10 or 30 minutes instead of 2 minutes only)
- Autonomy of relief (I will return)
- Functions, settings and parameters sufficient and easily accessible
- As a USB DAC, I plugged my tablet (with the kivabien OTG cable) and I have every imaginable apps
- Storage capacity in infinite reality since we can insert micro SD card 16GB

CONCLUSION:
In fact I love it for all I was not looking necessarily:
* Huge autonomy: not to worry about charging, no standby power (let him sleep eight days remain to almost 100%), recharge very fast, as well as via via usb charger.
* As a USB key: connected to a PC, clear management of files: drag and drop, rename, move, create (sub) folders ...

In short I have finally need anything other than this little gizmo that can lug around with his entire CD collection!
I stop here, I'm in love ;-)
