B&W 803D or Dynaudio C2's

I am asked by a friend to mine this question from the generous folks of the group.
I've given him the "go listen" and am asking for the model of his surround receiver to add to the post. But in general, can anyone give their impressions of these two?
Also, if there is a relative vg cond used market here, what other speakers would exceed the performance of these two in that price range.
Primarily, as I do not know that he will buy or have shipped anything used, comments of comparison on these two would be greatly appreciated.
Thanks!
