There are so many variables in putting together an audio system at that level. We don't know what brands you have available to you or what the room is like. It's not like buying a home theater in a box package. You want to pick your speakers and then fine tune the sound with the right electronics and cables.
I suggest finding a high end audio shop. You will need to use your own taste to determine what sounds good to you, They can suggest what will work in your room and install it.
