the narrator make a big difference to me too. While I haven't listened to this narrator in particular, I really enjoyed these productions lately on audible

Dune - has multiple voice actors

Star Wars: Heir To The Empire - happens after the orig trilogy, really good voice actor and also has some sound effects

The wheel of time: Eye of the world - Michael Kramer narrated really well here.

To Sleep in a Sea of Stars - Story itself was really captivating. Narrator Jennifer Hale was also fantastic
