ATC SCM40

With ringing in the New Year, I am thinking on trying the ATC SCM40 speakers. This is a huge speaker budget plunge for me but before I make a final decision, I want to see what you think on this model?  Currently I have the Vandersteen 2ci 

which they sound great powered by an Adcom GFA-5500 amp and a Rotel RC-995 preamp.
