If your stereo system just doesn't sound good enough, consider upgrading the cheap and nasty wiring between your component's and speakers, before going out to buy a whole new system.  While I would not recommend buying cabling that costs $100/ft, The Tech Zone has an article describing why when you spend $0.02/ft on cables, the sound may not quite be "live". 

"The very basic reason why audio cables are important is because they change the signal going

through them. There are two different, fundamental ways that an audio cable can change the signal.

The cable itself can change the signal, or the cable can allow outside sources of energy to change

the signal. In order to understand how these two situations can occur, some basic background

electrical knowledge is needed."
