I used a Boston Acoustics 2.1 (BA735 IIRC) system for over ten years and enjoyed my music a swell as watching movies and tv on my desktop.
If you want to increase your budget, check out Peachtree Audio equipment. They make integrated amps with DACs. They also make speakers (formerly known as Era Design) and compact systems. New, they are expensive compared to your budget, but they can be found used. I'm running a Peachtree Audcio Decco amp to a pair of NHT Absolue Zero speakers in my office. I also usea Peachtree Audio Nova and Era Design 5 speakers in my living room. No subs in either room and I'm very happy with the low end.
