I have a set of Bose that I got at a garage sale and they are the middle model 2.0 system. They sound just okay given that Bose is really not that good.
You never stated what you are playing as that too makes a difference on how any speaker will sound. I doubt they would sound better unless they are playing better quality files. You may want to consider other speakers that will give you much better sound such as the HK soundsticks, Klipsch 2.1 etc. If you are into good sound, cool factor and have the bucks, try the Focal offerings or go a step further and get the Orb offering for computers (speakers plus a mini amp).
