I have the Logitech z2300's. Man, do they sound good and get reasonably loud. Plus, the sub is an 8" //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
I have Logitech Z-220 2.1 (32W) which does the job. Reviews for Z-230 (which is basically the same thing) are like 100% if you go to Newegg or ecoustics. I can turn mine all the way up and not get any distortion. I'm also using an 11-band equalizer with my dbpoweramp player which makes all the difference in the world. I can turn Judas Priest or Black Sabbath or Nevermore all the way up and it sounds great. I can hear it all the way upstairs.
I'd like Klipsch 2.1 (200W), also. They're like a stereo system unto themselves. I read a lot of bad reviews about the Klipsch Ultra Pro 2.0 if you go to Amazon.com. They look great but I guess there are some problems.
