Since you are skipping tower speakers, you will want bookshelf speakers with good bass extension. One speaker I would strongly consider for your price range is the RBH PM-8. It's such a good speaker. It's a big bookshelf speaker, but it has tower speaker level extension and dynamic range. What is more is that it comes with its own amplifier, so you don't need to go out and buy one. All you need is a pre-amp. You can get different styles of composite stone for the accent panels, so there is customization in how it can look.
If you would rather have seperates, look at the BMR Philharmonitor. Very good bass extension for a bookshelf speaker, and an extremely neutral response.
McIntosh stuff looks nice, but be aware that its performance isn't significantly better than something that can be had for much cheaper. You are buying the looks, not actual sound quality improvements.
