>I'm fairly certain there's no DAC already at this point. The iPhone still has a physical speaker, doesn't it? Therefore there must be one.

  Doesn't mean it's connected to the lightning port - and in fact it's not.

      It probably means that the iPhone 7 can't output analoge signals via the Lightning port, so thre must be a DAC inside the 3.5-to-lightning adapter.
