I have the AVS500 system, but my laptop only has a simple stereo output, so I can't speak for the surround quality. As for the overall sound, I'm fairly convinced that there are better systems. The sound quality is good (not great), considering I only paid 40 bucks for it two years ago, but the subwoofer is a little underpowered, in my opinion. I've got it on full and there's still not enough bass unless I use the equalizer in my music player. Also, there is always a very quiet static hum coming from the satellites, even when the speakers are turned off. The only way to get rid of the hum is to unplug the power to the system, which, needles to say, is inconvenient. You probably wouldn't even notice the hum in day to day use, but I mention it only because I found it very annoying at night for the first few months I owned the system.
