The Dynaudio is the more dynamic speaker compared to the VA and Spendor but needs some power to sound its best.
I basically agree with Knownothing's comments as I own the Spendor S6e. Spendor does make a good speaker. But note that they are a rolled off on the top and bottom ends, may be too polite if you want to rock, and the upper bass is kind of thick sounding for lack of a better term...but they have a great midrange and have that addictive quality.
Sallie Reynolds of the Absolute sound did a review on the Spendor S8e, VA Beethoven Baby Grand and Moart a few years ago. Link is below which may give you some information that may help.
