I want to upgrade my current LCR speakers for better ones, however there are a ton of brands to choose from!

HELP ME!!
I typically watch 60% movies and listen to 40% music.
When I watch movies I want the new system to make me feel like I in the movie, I think that this is one thing my current set lack. I would like more of dynamic sound, and a wider sweet spot. One of my main complaints of current system is my center -- I hate it. The store said that it is a perfect match but I don't think so. It tends to be weak, and over all tonal sound doesn't match the fronts.
As for music I tend to listen to everything (except country -- no affiance)

I would like to hear more dynamics as well as clarity, and be able to turn up with out loosing clarity.
I know everyone’s next question -- "What is your budget?" Well I have 3 budgets listed below; please advise on the perfect set.
$1500
$2000
$2500
