I think I have a good example of the difference between the two audio formats for the people who really can't hear a difference. Grant it the over all difference is probably small, barely noticeable, if at all and I know the debates on that issue. However, i did a small test at home. In the movie jaws DTS version, right after the opening underwater sequence where the title comes up, we get a shot of the beach with kids smoking and singing, playing guitar etc by a bonfire. on the DD version you can hear hints of a fire crackling, but switch to the DTS version and WOW! bright crisp and clear crackling of the fire. I was amazed at the difference. Try it and you;'ll see. I don't know if it depends on the quality of recievers speakers etc.......... but would assume a difference can be heard by all. Let me know. Thanx!
