Docking station for an iphone


Is there a docking station that can retrieve the digital audio signal from an iphone to be sent to a DAC? 

mesch
sbank what options do you know of?   I like sound quality and convenience.   Might sacrifice some latter for teh former if needed.
I'm pretty sure that Wadia made one.  I think it was the 171i that worked with the iphones.
Yes but there is an adapter for the lightning connection of the later versions of the iphone. I use this and it works fine. I have my I20 running out to a Bifrost Uber extrenal DAC. Sound fantastic!
