For those worried about the quality of the dac in this unit.
Well fear not, i have one here right now plugged into my fiio e7 and superb is all i have to say.
The sound is imo about as good as you're going to get from such a device.
Currently listening to star wars medley 3 just as a quick test, wow is all i can say nearly as good as my hifi hp out if not better.
Impressive, most impressive.
I can take pictures if anyone fancies?
