Vernor Vinge. Output is bit low, but quality is excellent. Specific note: Tomas Nau in A Deepness In the Sky gets my vote for one of the more interesting characters and vilest fictional villain I've encountered.

Robert A. Heinlein. The Grandmaster.

Charlie Stross. Up and coming author whose future will be great, I think.

Neal Asher.

Iain M. Banks. He may be a Scottish communist, but he can write...

Greg Egan.

Yeah, Egan really requires full concentration.
