What type of computer sound do you have?

Just curious what type of system most people are using to listen to MP3's on their computer.

For instance, when you listen to stuff in the Listening Post...do you use headphones, the speakers that came with your computer, a decent stereo system like Denon or Luxman...or a regular system like Technics or Sony. Or do you have decent studio monitors powered by a studio amplifier. etc.
