Your list of audio books is very similar to how I started. I stumbled across a torrent with a bunch of Hugo winners, and those were included.
Some recommendations off the top of my head:
- Project Hail Mary (Weir).
- Snow Crash. (Stephenson).
- Cryptonomicon (Stephenson. Not sci-fi, but I highly recommend it anyway).
- The End of Eternity (Asimov. His only time travel book).
And of more recent date, the “Dungeon Crawler Carl” series as released by sound booth Theater is pretty much the gold standard in Audio book production. Seems pretty shallow at first, but the sci-fi element becomes more and more prevalent with time, and it weaves a pretty interesting story. On top of being hilarious. I cannot recommend this series enough.
In addition to those, Discworld makes for some great audio books as well.
I only know of the version I’ve heard on Audible, and that’s the Sound Booth Theater one (autocorrect butchered the studio name in my comment. Fixed)
