I am not geting into this fight, but i wanna say that i agree with Kryptum
I dont think that 3dvision produces dark psytrance
Its more like hard full-on. Those artists that you had mentioned play hard weird full-on music imo
Especially CPU and Absolum
Dark labels for me are the ones that dmtree sugested like: Sanaton, Apoxina, Schlabbaduerst, StoneAge, Parvati , Vertigo, and Mistress of Evil are all very good labels that produce dark music
