iPod/ITouch direct digital connection to a DAC


Any suggestion for an iPod dock that will take direct digital to a DAC?  I have not found any that are currently available on the market.  I tried a Pro-Ject Dock Box S Digital but for some reason the unit kept rebooting my iPod every hour or so; I sent it back.  Pure i20 and Wadia 171i no longer available either.  I am now using the iPod dock for my iTouch6 but would really like to bypass the internal DAC in the iTouch and use my McIntosh D150 for converting.  Thank you in advance for all replies.

The Apple camera connection kit which is the same as the lightning to usb is what you want.

Is there an internal software setting I need to look for to get this to work with the camera cable and my DAC?
Are you using iTunes?  If yes, make sure that the output is set to the D150.

If that doesn't work, try turning off the D150 completely, unplug the power cable.  Turn off your iPod all the way.  Turn both back on.

If that doesn't work, check the D150's user manual.  You shouldn't need a driver for an iPod.

Make sure the firmware is up to date on both.
