Lamm ML1.1 - enough power for Sonus Faber Cremona?

Hello,

Thoughts on whether the Lamm ML1.1 amps have enough power to drive the hungry Sonus Faber Cremonas (original version)? I've ruled out the ML2 series since I just don't think they'll be enough...sadly.

Room is 13 feet by 23 1/2 feet.

Thank you!
