I concur with the prior responses. Underneath the hood of many DACs is the same hardware that is in your CD player. You would have to spend goofy money to get an improvement worth writing home about. I think the $1200-1500 figure in the previous post may be low.
Demo some good speaker cables if you can, or upgrade speakers, or improve the room acoustics.
