Hi,
Now that you have listened to a set of speakers, go out and listen to some more. You think that the first set will work for you, okay thats fine. Now do some comparison shopping. Look for three more types of speakers in your budget and go listen to them. Then go back to the original set and see if you still like how they sound. I would also suggest that you take a CD, or better, a couple of CD's that you are very familiar with and use them when auditioning speakers. That way you will be able to better judge the difference that you here between speakers. I would do this even though you will be mainly watching TV. As you have read there are many different speakers out there, but let your ears be the best judge. Once you have it narrowed down to one set or maybe two sets, see if you can take them home to see how they sound in your room. If you like everything you hear after all that, then those speakers will be right for you, and then you can sit back and enjoy them.
Hope that helps.
