WHEN WILL THEY BE AVAILABLE?
They're actually available now.
To the best of my knowledge, there's only one dealer in the country that has them, and that's The Source AV in Torrance, CA. Cavalli Audio - along with Astell&Kern, Kimber Kable and Audio-Head - are co-sponsoring a Focal listening event there this coming Saturday, June 18th, 2016 (as the third of eleven events in the Summer Series 2016):

If you're in the area, please consider dropping by for an audition, and to hang out with us!
