As you seem not to be frightened by large books and also seem to like books with historic setting before scientific background, I would strongly recommend you the “Baroque” cycle by Neal Stephenson.
Not sure if there is a good audiobook version of it though…
Dune is a weird story mixing sci-fi, fantasy and religion, it isn’t my favorite sci-fi work, but it is a great work.
Neuromancer, the environment is fantastic, brilliant, but never got into the story.

Interesting, thank you!
