Ipad connection to BMC DAC1

Hello BMC DAC1 users,

Is it possible to use Ipad as a source using the DAC1 USB 1.1 input? My intention is to use DAC1 as a preamp (via balanced XLR) and DAC function. If such connection is possible perhaps I need to find a reliable lightning/USB 1.1 (USB 2.0) adapter.
I saw a review on 6 moons mentioning Teac DS-H01 S/PDIF cable connected to the DAC1 but the Teac is now discontinued and its docking is for old Ipad 24 pins. I can use the Mirage AVR SR7008 for air streaming but it is a 
big machine to add to the rack just for streaming function. 

Thanks for your help and happy holidays!
