Couldn't agree more :)
Sven Vath and specifically his producer Ralf Hildenbeutel on the Harthouse label were the early pioneers of the hard trance sound. Artists such as Resistance D and Arpeggiators pushing up the BPMs of trance to 150+
A contender for me has to be this:
YouTube - Cybordelics - Adventures of Dama
or especially this classic which at 170 BPM was the hardest trance tune of the time:
YouTube - Curare - Schneller Pfeil
