This is what annoyes me sometimes, is that many people believe that one must be better than the other. Have you read both reviews for a start? Which one has a sound do you think you would like the most?
Personally I have never heard the Eclipse, but it is a single driver design, which means it will be limited at both ends of the frequency spectrum, both high and low.
If you like your music at low to medium volumes, with no bass, but like the midrange, then try the elipse.
If you like a full sound, nice top, nice everything, get the Dynaudio's.
Personally I would buy the Dynaudio's. Plus If you dont like them, you are more likely to find someone who will buy them from you again.
