I'm glad to be of some assistance. Masi has great offerings but there is very little information on the net about them. I enjoyed my time on the CXRx and still ride an Evoluzione Disc.
Now, that said, I have 1,500mi so far on the Hakka and consider it the best bike purchase I've ever mad. Just in the last couple of months, I have set it up to be a quiver killer. I'm running Rival1 with a 42t up front and then four wheelsets to suite my ride:
Ibis 733 wheels, 11-44t, 27.5x2.1 Thunder Burts - fun adventures in the Santa Cruz Mtns
Mercury M5 wheels, 10-42t, 700x32 Specialized Roubaix Pros - road rides solo&group
Mercury G1 wheels, 11-42t, 700x35 Kenda Happy Medium - dry CX racing
Mercury X1 wheels, 11-42t, 700x33 Specialized Terra Pro - muddy CX racing
I honestly can't say enough positive things about the Hakka, I absolutely love riding it!
