I don't think there is any difference than the dome color. ADC is anodized black, CDC is anodized white. Perhaps CDC is little more expensive due to more scrap parts in production, as more white domes might get sorted out due to beauty issues.
From the published measurements I found I cannot see deviations in performance and behaviour exceeding expectable production tolerances.
In German Hobby Hifi magazine both were tested, and the author Bernd Timmermans stated also there is no difference than color, so he recommends to take the cheaper ADC...
