Klipsch Pro Media 2.1 vs Altect Lansing MX-5021

Which one is better? My requirements/conditions:

1. Has to be 2.1 or 2.0
2. Preferably should be one of these two. (Please suggest worthy alternatives if you are aware of any)
3. Will be used with a dedicated sound card.
4. Should have a TIGHT low end with absolutely ZERO muddiness/cheap boom factor.
5. Main music type: Eurodance/Trance/House
6. Finally, money no bar.

Waiting for some suggestions.
