There is no more important factor on the way your room sounds than your room acoustics and don't let anyone tell you any differently. Expensive, reference-level AV gear is worthy of lusting after but far less expensive equipment can sound simply fantastic in a property treated room. And by "properly treated" we don't mean that you have to spend $10,000 or more on tricky equipment, design gurus and more. Simply adding absorption on the first order reflections (the areas on the walls and ceiling about three feet in front of your speakers) can make a huge difference in your sound. Adding some bass traps in your corners can tighten up your bass in ways that no gear upgrade can do.
