and I'm in a good position to try it: I'm using the HiFi-M8 on my desktop
(via my MacBook Pro SSD/Amarra rig, goin in USB - and using Mad Dogs balanced).
I tried hooking up my iPad to the USB DAC/computer input via the cam connection kit and USB cable,
But, I guess for this version that makes sense, perhaps its in order to meet Apple approval (maybe its a part
of the approval process that you can't allow tricks like this, since you can just hook up the iPad/iDevices
on this version and go).
But, it was interesting to try!
Now I'm using my iPad as a source though (going in thru the iDevice input)!!
