Hi. I'm looking to buy a 5.1 speaker system and AVR all for under $1000. I live in Australia and the speakers are for a dedicated home theater room. The size of the room is around 4 meters by 6 meters (approx. 12 x 18 feet). Please list any and all systems that you think are good for this set up. My main concern is getting good sound quality for the price - I'm not into Airplay or any of that fancy stuff. Thanks for your time.
