Firstly the room size is 21 ft by 15 ft (7mtrsx 5 mtrs)approx.

I will be using the system for movies,music snd have foxtel connected.I will be using a 50" flat screen Plasma which is mounted to the end wall. My previous setup which hasnt been upgraded in a while was using a Denon receiver ( avr-1801)
Bose speakers and Tannoy Sub. I am moving them all on for a new setup. Im in the process of searchingfor a new Receiver - must have a few HDMI inputs and atleast 1 output.

So really I still need to settle on a receiver , main-center-rear speaker setup and a sub.

I feel you guys will have a heap of experience with all types of setups so could probably pass on better info than the man from the shop trying to make a quick sale!!
