Disclaimer, I'm a dealer.
If you're serious I suggest that you contact a knowledgeable dealer and let them put a system together within your budget to audition. Otherwise you're going to get a myriad of suggestions here that will only add to your confusion. Just a couple of points to keep in mind whichever way you decide to go, you ought to consider your room size and acoustics when looking at new speakers. 2nd, don't waste any of your budget on high priced cables or worthless tweaks.
