Audible is absolutely epic.

On audible, I highly recommend lectures from The Teaching Company / Great Courses.

Great narration: https://www.audible.com/pd/Platos-Republic-Audiobook/B01CO38..., https://www.audible.com/pd/The-Art-of-War-Audiobook/B00URXOQ... (familiar voice to you?)

I've also had one of the worst narrations I've ever heard: https://www.amazon.com/Monkey/dp/B0162SWL4G/. I believe it was delisted on audible.com
