iPhone into Bel Canto 2.5 ??

I'l love to run Tidal off my iPhone into my DAC 2.5.

I bought an Apple Lightining to USB adapter to plug it in, but the DAC 2.5 won't recognize it (reads LOS on the display)

Any thoughts?

Would it work with an Amazon fire tablet?

(I know a computer works with the 2.5, but I don't want my living room to look like an office).
