Choosing between ATC or Emerald Physics

In the upgrade process of a secondary system for the living room, I'm planning to change the speakers. Actually the components are: a tunned Oppo as transport, Paradisea DAC, a recently arrived Wyred 4 Sound STI-1000 integrated amp, Opera Mezza bookshelves... the matching is excelent and the system sounds very, very good with the new amp.

Previously I selected 2 speakers: ATC SCM-19 and Emerald Physics CS3. Now I have to choose between them... any suggestions ??
