Documented the heck out of this in my thread above.

The Carsara unit there is a noticeable quality improvement going from Aux cable in the console to rear of the headunit.

I would expect the same regardless of the unit you choose. But it can be hard without taking the time to compare them back to back and having them EQ'ed. I lived with my unit pre-coding for a few months then coded it, and at the high frequencies the improvement is noticable.

Audio over Aux will never be as good as digital via the Combox or CD. But it's completely fine in a car with such poor sound deadening.
