Sonus Faber Cremona vs Guarneri?

I read a few threads on the new Cremona but would like to know how it compares with the Guarneri. I own a pair of Guarneri and will be moving in a few weeks. My new listening room will be 17'w x 20'd. I like the musicality of the Guarneri but will need more bass to fill my new room. Does anyone had the opportunity to compare both models?

Thanks in advance
Daniel
