It seems that, in a similar way to movies, there is no waranty that a good book will be turned into a good audiobook. I've realised that after listening to some of the best sellers books recorded as unabridged audiobooks. In particular in The Caves of Steel by Isaac Asimov narated by William Dufris, the female voices are so awful, that I can't belive I finally finished the entire audiobook.
Looking for the best narrators, I stumbled with a couple of web sites that list the so called "Golden Voice" narrators. Maybe an equivalent to the "Academy Awards" for audiobooks.
This other post was the reason why I choose to post the question here, since It may be of interest to some writers.
