To get sound quality to match the Ascends, you'd have to go ID. That puts you with Aperion and Axiom at that price range.
Do you have a good sub already?
The Ascends are sweet speakers, though, although not as nice to look at as the Aperions or Axioms. I myself got 3 340s, 2 170s and a HSU VTF-3 last week and I couldn't be happier with the quality. I spent some time tweaking sub placement, and it sounds absolutely great.
The Ascends are going to be more neutral, and the Axioms may be a bit brighter, and the Aperions will probably sound a bit different as well. You could always get a left/right pair from the brands you're thinking of and compare them in your home. Or not...
