I can relate to your enjoyment of hi-end acoustics. I have a Boucher BG52GM, which I prefer to Martins as it is still warm but clearer in the bass without emasculating the bass like so many guitar makers do who describe their instruments as "balanced".
The OP's wife will be shopping at a much less exalted price point. The question will be whether she can find an inexpensive guitar that she finds comfortable and sounds good to her.
So, did your wife find a guitar?????????
