Hi. I just bought a HDA Mystique and my current sound system doesn't do it justice. So I was thinking of upgrading sometime in the next 6 month. So i figured I'd start the trek to a good affordable sound system now by asking you guys what's the best i can get with the money I have and what I'm using it for. I'm thinking I won't go over 600 dollars for everything you need for a descent 5.1 surround system Minus the sub. I've already got a pretty descent sub for the size room this is going into. I'll be using it for music, movies and gaming. Suggestions, recomendations and links appreciated. Thanks in advance.
