Hi guys i am looking for a 2.1 speaker system. So far i have shortlisted these HERCULES XPS 2.1 20, CREATIVE INSPIRE t3130, LOGITECH Z313. My requirement are that speakers should sound crisp and the bass should be tight not boomy(i really like bass). I had a F&D A520 which suddenly stopped so i have returned it i am looking for a replacement.THANKS
