What is the best speaker system for Trance music.

I love trance music. So much that I’m going to save about $200–250 to buy some speakers (or maybe headphones) for my computer to play it really loud. I’d really like answers from people who know all about Trance music and already know how frustrating it is that so few speakers seem to play it correctly.

My favourite artists are DJ Tiesto, Armin Van Buuren, Smaul Paul, and Peter Sonix. If you know these artists and know a lot about speaker systems to play them just right, please respond.

I want something that I can plug into my computer, preferably with two monitor speakers or satellites and a subwoofer. I’d also like to be schooled in what to look for in a speaker system in general. What are the quantities and measurements associated with speaker systems that make a difference, and what do they all mean?
