Sonus Faber fans: Liuto vs. Cremona Auditor M?

I would like to hear some opnions about these two speakers as I will be upgrading from my concerto domus speakers. I planned on going to the cremora Ms, but would like to hear more about either speaker if anyone has any opinions or has compared them.

Miner, thank you very much for your detailed respose. I would be buying the floor standing cremoras. I have been using Pathos integrated the last two years mono-blocked with ny concertos. I have been very happy with that combo and have heard the cremora ms with the patohos and like it very much. Obviously, the Liutos are cheaper, thus my question. I haven't been able to hear the both together. You have been a big help.
