haycheng: I don't think that there's a good answer to your question, as long as you don't answer a few questions, because...
- as long as we don't know where you're located at, we don't have any clue about really good offers in your area
- as long as we don't know about your listening room size and desired sound pressure level, we can't tell you what speaker type and what amplifier wattage could be appropriate
- as long as we don't know whether you have a heavily or scarcely dampened room (do you have lots of carpets, curtains, sofas comfy chairs or a minimalistic designer room?), we can't possibly know, whether you need loudspeakers with lots of or recessed highs
- as long as we don't know what media you want to playback, we don't even know how many and which type of components you'd need.
So don't be discouraged, but give us a little more clues, instead - and then you should get resonable recommendations accourding to your needs. Otherwise you'll just need lots of good luck.
