Is the name Audrey too old sounding?

Is the name Audrey too old sounding? I was pretty much set on Audrey Kathryn for my daughter, but now I'm starting to think it sounds a little old. I know we want an A and a K name (for both our grandmas) what do you think? Plus it's kinda difficult for my parents to say. Should I stick with it and just call her Addy?
