Reddit reviews Eater

Gregory Benford might be to your liking, Eater hits a lot of those old hard SF buttons in particular. The Hyperion Cantos may also do the trick. C.S. Friedman's In Conquest Born and This Alien Shore are favorites that have that classic sci-fi feeling.

I would also give Stephenson another shot.. it's really good stuff, but yeah Snow Crash is a little over-the-top (very much so for the first chapter or two, but it does settle down a good bit). I mean, the main character is named Hiro Protagonist... there's obviously going to be a certain level of tongue-in-cheek, self-aware ridiculousness going on, but it's quite amazing how well he foresaw much of the modern computing world. Cryptonomicon is awesome and is one of those rare books that somehow feels like science fiction even though there's nothing out of the ordinary in it. Anathem and Zodiac are also quite good and more traditional in tone and style.
