I have some suggestions for you at home. I am a complete techno/ hard techno addict.
All I can tell you for the moment is that Jeff Mills Purpose Maker Records, Carl Cox F.A.C.T and Ritchie Hawtin (aka Plastikman) as well as Dave Clark have made excellent pioneer stuff on albums and lives.
Now, if you want something harder, try Jeff Mills Axis Records, Technasia, or Sino Records, for instance.
If you're more in trance, check Transcescape compilations, Bonzai Jamai Records, Dominion, Teck Clock Productions, and more Swiss stuff.
Finally, if you're a hardcore guy, try Happy Hardcore, but also Thunderdome, Cyberpunk, RTC (Rotterdam Terror Club) Records.
If you are more in d'n'bass, speedcore, or progressive, experimental and ambient, I have some more advice. But throught the compilations, mixes and lives I just recalled, you should already be able to listen to a LOT of other good stuff, records, labels and so on.
My own preference goes to Axis Records, Jeff Mills 'Circus' record
