You need to listen & feel yourself bro. Go to the nearest AV shop for audition. Got 2.1, 5.1, 7.1, etc... For RM2000, perhaps only HTIB. I suggest you to save more $ to get a decent 5.1 setup. Just a price indication for 5.1 setup, AVR - RM2k, Speakers - RM3k, Subwoofer - RM2k, Cables - RM500.

KLAV show is coming soon, look for other tread for details.
