I can't help you with Focal Bretty, but yes, we have the CXA5000 and MXA5000 on demonstration, and it was the centrepiece in our main AV demo room at our open day last year (along with Sony's VW500ES Uktra HD PJ). Many will know that I prefer Yamaha's processing with regards to films, as their effects steering tends to be superior, and their soundfields seamless, and far more convincing than many of the competition out there. If I could afford a CXA5000, I'd have one in my system right now, especially as I have no intention of moving to Atmos or any other format for a few years to come yet - I'm quite happy with 5.1, and my room doesn't warrant anything bigger. I'm not keen on some of the 'auto' or 'progressive' features, but then I'm no fan of them on any manufacturer's products. Its YPAO is decent - not up there with the best, but flexible enough for most people, and it EQs down to 31Hz. I always thought Anthem's ARC was good in the way that you can set a high pass filter for EQ, and thought it was on its own in this respect, but you can go into the set up and change the EQ manually to be flat (no EQ added) from any point upwards you like. And all this via a URL on your computer or tablet.
