ain't that much choices with that much budget. maybe could get you a sub though..
try and visit some hifi shops. search around and listen first. they won't charge you for an audition. get the feel of the sound signature and see which suits your taste as sound signature varies quite a lot from model to model.

and owh, do take the recomendations with a pinch of salt as people have varying amount of preference. best if you could listen and find your own taste. might not suit others, but who cares as long as you like how it sounds.

and another thing, do search for used items traded in at the hifi shops. you might find a good deal there. but don't hope too much lah hehe

after listening at the various speakers at hifi shop, I bet u will buy some go home with something way above ur budget....
