Lightning to 30-pin adapter accessory compatibility and DAC question

[floss]

Specifically, i'm wondering if the adapter will work with this cable: http://www.amazon.com/MPI-Audio-Cable-iPhone-Connector/dp/B003L13BNI/ref=pd_cp_cps_1

I used it to connect my iPhone 4 to the auxiliary port of my car. It gave me line-out audio amplified by my car's sound system, which is much better than using the crummy headphone port of the iPhone. Now that I have an iPhone 5, my only solution would be to buy a lightning adapter.

If it does work, my second question is: would the outputted audio use the iPhones DAC or the adapters DAC? (Apple stated that the adapter has a DAC implemented in it, which makes it a little confusing)

That cable should work fine in theory. The adaptor has a DAC, the iPhone dock port has no DAC.
