Is this for headphones or speakers? In other words do you need a head amp included with the DAC? And more importantly what is your budget?
I just dug this list out (thanks to ccfoodog of head-fi - ori post here (http://www.head-fi.org/t/507559/list-of-dacs-that-work-with-ipad). I will paste the main list below.
There's more info on the above link about power. I'm sure I heard somewhere that the Audinst HUD-MX1 works, which is not on the list. I have that one but I don't have an iPad so I can't test it.
