However, Apple sells a dock for the new devices that includes a Line Out plug. http://store.apple.com/us/product/MF030ZM/A/iphone-5s-dock
It has been speculated that that dock must include a DAC that converts an analog Line Out from the digital lightening connector.
So... Is there a way that this digital output can be directly captured from the Lightening Connector for input into higher-quality DACs, etc.?
