If you can swing an extra $100, www.saturdayaudio.com has a pair of demo Monitor Audio S2's for $399. They normally sell for $750pr. They are very good speakers and will be hard to beat at that price. Others to consider would be the PSB B25's that are on sale at audioadvisor for $299pr.

These are both larger bookshelfs and are well worth the money. I would also consider getting a dedicated Cd player like the Marantz 5003 or a used 5001.
