AUTECHRE! These guys are the true wizards of techno today. Along with Aphex Twin, they have set the standard for what techno is and can be- that is, highly complex, highly subtle music meant for serious, sustained, unstoned listening (as opposed to dancing). Check out in particular Autechre's _Tri Repetae_ and _Chiastic Slide_ and Aphex Twin's _Richard D. James_ and _Selected Ambient Works Vol.II_. There are lots of other decent, interesting techno acts which can sound surprising good on a high-end system. The Future Sound of London, Orbital, even Underworld and Moby, come to mind. I am also quite enthusiastic about the later releases of the dark ambient dub act Scorn. But if you want to find out what techno is really about, the ultimate refutions of the "bleeps and beats" cliche are Autechre and Aphex Twin.
