If you don't literally mean D&D audibooks, but merely good fantasy audiobooks, in no particular order:
1) All three volumes of the "Magicians" novels by Lev Grossman
2) Any Neil Gaiman audiobooks that he reads himself, especially "The Truth in a Cave in the Black Mountains," which is included in "Trigger Warning"
3) "Throne of the Crescent Moon" by Saladin Ahmed
