When I started listening to the Harry Potter series on audiobooks, I began with Stephen Fry as reader. And I LOVED him. But some people kept telling me that Jim Dale was much better. I couldn't really imagine how he could be, and I was so satisfied with Fry that I saw no reason to switch. Well, there were some technical problems half-way through Chamber of Secrets, so a friend who works at the library reserved their audiobook for me so I could finish the novel, and guess who's the reader? Right. Jim Dale. So now I can speak officialy on the matter.
Stephen Fry is the best. Hands down.
