Schranz (IMHO) just another name for hard techno, as said before... My impression of schranz still is the 150 bpm monotone pounding beatz without any depth of content.

DJ's / Producers: Rush, Frank Kvitta, ViperXXL, Amok, Ogi, Daniel Gloomy are to be labeled in the schranz-section... But yeah... it's all just "too-hard-&-too-fast-techno" for me
