This is the first thread that I looked into:
then just trying to figure out with the CCK + powered USB hub + DAC, I stumbled upon this thread:
......brilliant, the "powered USB hub" might be the key here next to the CCK.
I haven't yet tried my mini iPad with lightning connector adapter to 30 pin + CCK + powered USB hub + DAC.
OR just connect your iPad to Cypherlab -R, might be the safest route but a bit pricey. They have validated that their DAC are compatible with the new lightning connector.
Hope those help.
