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.

I use the NuForce iDo. They are no longer available new, but you might find a used one, or NOS, on eBay or Amazon. I use mine to provide bit-perfect digital output from various iPods, iPhones, etc., to my DAC. It is also a very good headphone amp if you need that.

I've used mine with Apple gen 4, 5 and 6 with no issues.
Get a lightning to usb cable and a power supply and your in business. Thats what I use and it works great.

I use the Apple camera connection kit to output digital from an ipad/iphone to my Schiit Modi Multibit in my car. The output of the dac goes into the auxiliary input in my car. I use the Onkyo HF Player iOS app to play high res files. The Onkyo HF player also has an awesome equalizer that is desperately needed in a car system. I also use the W4S Recovery before the DAC.

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