I remember as a kid all the theaters were advertising their sound systems. Half were THX-certified, even those that weren't were making a big deal of their new digital sound systems. I can remember always seeing DTS, SDDS, or Dolby Digital trailers before movies started. Now it seems no one shows the trailers and all of the THX theaters have lost their certification. There's not a single THX theater in Dallas, and only a handful in the entire state!

I think it is pretty expensive for theaters to license and lease the equipment from THX, so many theaters may have opted out in order to save money.

In Vegas, we have six theaters (out of twenty) that are THX certified.

BRENDEN PALMS 14
CENTURY SAM'S TOWN 18
CENTURY ORLEANS 18
CENTURY SOUTH POINT 16
CENTURY SUNCOAST 16
CENTURY SANTA FE STATION 16

However, the best theater currently in the city is actually not THX certified. The Galaxy Cannery 16 has amazing sound and all the screens are equipped with DLP. If the theater wasn't 35 minutes away from my house, it would probably be the one I go to all the time.
