I have a Denon amp with Acoustic Energy speakers and MJ Acoustics subwoofer,which is a decent set up I believe.
But it all depenRAB on the mix.
There have been numerous old movies remixed into DTS.
The latest Bond discs have superb DTS sound on the 60's films,yet the 60's horror films from Amicus remixed into DTS from Anchor Bay are awful,so DTS is not always better.
In the very early days of DVD , the only way to get DTS was on its own dvd with no extras and no DD 5.1 sound as the full bitrate DTS took up so much room,but a while after low bitrate DTS was brought in and the argument about less compression on DTS was lost,although it did allow DD and DTS on the same disc like we get today.
Some DTS mixes are dreadful,but so are some DD mixes aswell.
However,most of the "DTS is better" is simple snobbery and most would never be able to tell the difference between a DTS track and its DD equivalent if they were blind folded.
Having said that ,if a DTS track is present its the one I usually listen to purely based on its history as a technically superior format.
