Thanks for the insight Rbinck, as usual, you intimidate me with your knowledge. I did a little tinkering with my 2 sound systems. My computer has an older Hercules 7.1 (which I love) sound card in it. I also have a cheap set of Creative 6.1 speakers. I played the movie "21 Grams" and did notice a "little" enhancement to the sound quality of the movie due to the rear center. I then played it in my home system (Aiwa receiver 5.1 + dts - jensen center, sub & rears with jbl pro-monitors up front). I then asked the wife and son to watch the movie on both systems (without telling them what I was doing) but asked them to pay particular attention to the sound. They both concurred that they could not tell a difference (other than the obvious jbl pro-monitors). I then told them what I was doing and they listened again - with conflicting opinion. My son thought the 6.1 was an added bonus when my wife vehemently said that the rear center was a distraction. In conclusion - I started a fight at Oblioman central.
