I got a cheap lightning to USB (female) adapter from Aliexpress. I thought I would be able to use flash disks through this adapter, however my iOS either said it required too much power or that it didn't know what to do with a plain drive. It needed an app obviously.
Then, I tried different type of devices and managed to have a Asus Xonar U3 USB sound card and a self powered Fiio Dac working perfectly. I tried my 150 Ohm Superlux headphones with Xonar and it really can drive them with the power it gets from my iPhone 5s.
Fiio can do 96k 24b, BTW.
