i have the logitech z506 and a sound blaster z sound card but i dont get that much of a surround. I am watching from netflix with dolby digital plus decoding which i get i dont have it with this sytem. So i wonder is that what i have a surround sound or it gets better with better gear? If so is the difference noticeable a lot or its something audiophiles can see. I just want a good surround sound system for my movies. On cinemas i see a difference from my current setup though and i am talking about how the sound splits into the 5 speakers and afterwards about how clear it is because clearness is not that much of a difference i belive
