Reference 3a MM vs De Capo vs De Capo i

hello all!
I want to know your experience between each of these 3 versions of this incredible speaker. what can I expect? is the i version worth the money? how good is the original? mucho appreciated!
You can read the reviews on the De Capo and the De Capo i at The same reviewer reviewed both, and gives his thoughts on the differences.

I have only heard the De Capo i's, but I've sat down with them many, many times, and I really like them.
