Hi,
There is a dealer here in Atlanta that carries both (Earthshaking Music, which deals primarily in pro gear but also has a hifi room). I've owned the non-i de Capos and heard both the de Capo i and Cain & Cain Abby there, but I didn't audition back to back. The Cain to me sounds more like a planar speaker, wide, deep soundstage, open sounding, esp. the standard version of the Abby, which I preferred over the higher eff. version. Very smooth sound, great for jazz, chamber & vocal music etc. The de Capo also images well and is open-sounding, but to me a little more more dynamic than the Cain. Moreover, I think the i-version is slightly more dynamic than the non-i version that I owned, but IMO still not enough for large scale orchestral music. I'd have to hear both back to back on the same system to tell you more. Good luck,
