The lightning to 30 pin adapter apparently had 2 DACs in it, and it was a lot older and not much much bigger.

I don't think there are dedicated pins for audio in the lightning, so a passive adapter doesn't seem like it would be possible. I guess it would have to have an amplifier built in too? That's a fascinating little adapter if it actually works well.
