Proac One SC versus De Capo i. Opinions please?

I was very close to getting the Proac, but it seems the De Capo has a lot of admirers. I can't get to audition the De Capo, but I'd be using it with my Sugden MusicMaster amp, 16w, Class A.
Has anyone got first-hand experience of both these speakers for a comparison?
I'd like to hear your opinions.
