Dynaudio Confidence Speakers -Old and New?

I'm using C2 Platinums, but haven't seen any direct comparisons between that generation of Confidence speakers and the new one.  Perhaps I'm not looking in the right places.  Please point me in the right direction if I'm not.   I've heard the C50's but not in my system.  My instinctive reaction was that I preferred the C2's but that's not a reasoned opinion nor is it  based upon a fair comparison.  Just curious if anyone has listened to both the new and old Confidences  and what their reactions were.
