Im trying to find something I can travel with on long flights that would give me a big boost in audio quality when watching movies on my ipad. I would be using 30ohm headphones (B&O H6), and some times daisy chaining my wife's pair into it (no need to have two outputs on amp as the H6 can connect second set of phones off one another). Im not sure how power ratings are measure and if that means id now be at 60ohms?
 
Anyway, I want something that provides a good amount of power, can connect to an iPad digitally so I can use a better DAC and is self powered. I dont want to have to plug the amp into another unit via USB to run it. 
 
Anyone find anything that meets similar specs? Lets say budget is $250.

Look for a used Centrance DACport.  MSRP $399.  iPad support.  
 
EDIT: not sure if this is still the best option in light of the new Oppo.  feel free to ignore me.
