The paradox of choice. It paralyzes me too, and I certainly appreciate the theory that less can be more.
I'm a newbie to audiobooks too. I've listened to them for years and years but not in significant quantities until the last 2 years. I have learned
a lot about narrators from following threads in the Audiobooks forum and seeing what narrators or publishers people recommend. Also, when I find a narrator that I really like, I look at what else is in their catalog. Another tip is to look at what audiobooks are at your local library to reduce the choice.
In this case, I saw John Lee's name and knew that I had listened to him read classics in the past. Also the majority of classics that I have are Blackstone audiobooks. I also have several Tantor audiobooks. The two other publishers that I like for classics are Recorded and Brilliance. Lastly, I really enjoy the special Audible versions of the classics read by famous people such as favorite actors of mine.
Hope that helps!
EDIT: Just looking through my audiobook library, I also have some classics published by Naxos.
