Rick always seems to give the appearance that he loves all his children equally.

If you call Rick, he is more than happy to discuss things with you and based on your situation he will help you choose a design that should be good for you. He just seems a bit reluctant to show favorites in public.

I considered the Prestigio, the Cima was out of reach as far as $$$.
For myself, I have never heard any of the three, but after exchanging e-mails and phone calls with Rick. I am about to get an extended audition of the Grandeur.

Part of my decision to go with a Grandeur was that I was not planning on using it for home theater, and we don't listen at loud levels, so an MTM like the Cima or the Prestigio was probably overkill, and the single woofer Grandeur was a bit more financially friendly.
My guess is that all three would sound excellent, but based on listening habits, and preferences Rick should be able to help you decide which one would suit you better.
Cheers,
Chuck
