Based on logic, it is CERTAIN that this thing does include a DAC, why?
 
This adapter works on every iOS device since iPhone 5. If there are modifications allowing iPhone 7 to output analog signals through Lightning, the modifications certainly cannot be on iPhone 5. So the DAC has to be inside the connector.
 
All you need is a Lightning interface chip/DAC combo, which can be put inside the Lightning plug, then the front amps for headphones, which are usually on the audio jack flex (check iPhone dock flex assembly or iPad mini audio jack assembly). It may be a challenge to shrink them to fit into this adapter, but it is still possible.
 
I'm more interested in audio quality though. Can this thing be at least on par with regular iPhone audio jacks?
 
The following is the lightning interface chip "Tristar" on iPhone 5. There is no analogy audio signals connected to the chip, so it is not possible to output analog audio through Lightning at all.
