Techno trance is hardly uplifting. The only elements it may use that is considered 'Trance' in any way is similar synth sounds used in Trance and trancey-sounding basslines. Some do bend the rules and have mildly uplifting melodies however.
Labels of this ilk to check out are:
Antler Subway - Belgium
Hard & Holy (varies) - Germany
Headline - Germany
Byte Progressive - Belgium
Brain Recordings - Germany
Deep Mission (varies) - Germany
Monotone - Germany
Pulsive - Germany
Sacrifice (BXR sublabel) - Italy
Seismic - Holland
X-Trax - Holland (but I'ms ure you know that anyway)
There's some great techno coming out of Italy and Sweden too,it's just a matter of finding them...
Happy listening
