Sonus Faber Center - Domus or Liuto Smart?

I currently have a pair of SF Concerto Home Monitors as my main with 4 SF Walls for surround. I would normally try to match the SF Piccolo Center with this set up but these are hard to find. I have the chance to buy either the Domus Center or the Liuto Smart; which is a better match?

I assume both would be acceptable but which would you pick?

It is likely not a factor but my concertos and walls are all 6 ohms; the Domus center is 4 ohms and the Smart is 8 ohms. The Domus has a mid and is larger. I have not heard either center.

I have mainly listen to a wide variety of music but want to start using the system for movies and want clear dialogue.

Thanks for your help!
