I just finished my re-read via audiobook... and LOVED it. Narrator Juliet Stevenson is just perfect. There's something about the dialogue in Austen's books, but perhaps especially in Emma, that just begs to be read aloud. Hearing the different voices was hilarious, especially the quirkiest ones like Mr. Woodhouse, Mrs. Elton, and Miss Bates. 
 The story is wonderful, of course, and I'm so glad to have had the pleasure of listening to it!
