If you've been used to the more upright position of a hybrid, the difference in geometry on the Audax might be making your neck ache. I found the same thing at first when I went from a hybrid to a road bike, but once my neck and shoulder muscles strengthened the problem went away.
If you really don't like this bike, and it seems that you don't, why not return it while you can and go back to the cycling you were enjoying before? People tour and do all sorts of long distances on hybrids, usually for this very reason - they prefer the more upright riding position.
I wondered if I just needed to give it more time to get used to it. The bike rides very nice, very smooth and certainly a lot easier to get up hills than my old bike which was a dreadful slog.
