I had my own personal narrators for these books...my parents read them to me as bedtime stories.
I have the version read by Harlan
and Ursula LeGuin. You may need adjust audio setting for best sound Otherwise the performances are really good (48kbps). The same is true for book 2 (Gabrielle de Cuir)(also 48kbps)
Book 3 is audible (48kbps), audio is clear and very good performance by Scott Brick and Ursula.
Book 4 is a cassette recording, flat and tinny (48kbps) read by Robert Donley
Book 5 read by Scott Brick and others, you may need adjust audio setting for best sound(48kbps)
Book 6 read by Scott Brick and others, you may need adjust audio setting for best sound(48kbps)
I don't have book 7.
