Since I got my new earphones, my PC speakers are really lacking. My earphones are excellent - fantastic sound quality and a built in subwoofer. So i'm looking at getting some new PC speakers to bring the quality to my PC. I've looked around on ebay and computer store websites and have hundreds of different options, but as i've no idea on what speakers are good on quality. I'd prefer something with a sub. 5.1 or 2.1. But i want something that has very good sound quality. Any ideas?
