I think certain flavorings can amplify, rather than mask, the flavors of fruit. Ginger with stone fruit, for instance (or almonds, which aren't quite a spice). I also love a tiny, tiny, tiny hint of rose with strawberries.
That said, too often any of these flavors are added too heavily.
My pet peeve is actually over-mixing of fruits -- I know folks love strawberry and rhubarb together, but to me the flavors of each get lost. Ditto for a lot of "mixed berry" concoctions that aren't as good as a single berry.
