BEST SO FAR BUT I AM NOT AN EXPERT

I had a regular surround sound system from Best Buy. I had it connected to a 5.1 sound card. It went out on me after one year. I bought 4 other supposedly upgraded sound systems and they didn't sound and better than the cheap one from Best Buy. So I went to Fry's and told the computer tech that I wanted to put a movie in and when it something exploded I wanted to feel it. That is something I have never experienced. He said "follow me." I did and he pushed this button on the display and something came out that I had never heard before, actual undistorted sound. More clear than the floor speakers I have in the den. I am extremely cheap so i went over to the home theater section and tried their most expensive systems and they didn't sound no where as near as good as these. So i had no choice. I walked my tail right back over to the computer section and got the Bose Companion 3. I have never had anything like these before. I never really cared about sound but once that salesman pushed that damned button, I couldn't go back. Also I can hook up my headphones with built in microphone to the little control pod without getting on the floor and hooking it up to the cpu. I have no complaints so far. I did experience some hissing but I adjusted it by going to my sound card feature and moving the arrows. Don't know what I did, but it worked.
