What is the best amp for Sonus Faber Cremonas?

I agree with the 1st response, try a different pre amp. I would go SS and yes try a Mcintosh, I have owned both the c2200 and the c46 at the same time, thru my Mac 252, I prefer the c46. to me it had more guts without being bright and had more definition.

There have been some comments on the dark sonic signature of Sonus Fabers which are spot on. However, this is only applicable to the the lower lines in Sonus Fabers. They are very coloured speakers, certainly not neutral with a glorious midrange and rolled=off highs as some has suggested. Absolutely wonderful on vocals but doesn't possess the speed and transient attack on some materials compared to more neutral speakers, and some highs might not be reproduced as convincingly. PLay some piano tracks and you would notice the sound is somewhat not quite right.

The higher end models Amati Homage or Stradivari don't show these faults though.

Krell has always been a good amp to counter the warmish character of the Sonus Fabers. Have seen many driving Electra Amator I & II as well as GP's and Cremonas.

I disagree my sonus faber cremona speakers sound fantastic with my Mcintosh C220 pre amp, MC252 power amp and MVP861 cd player. The sound is fantastic. Maybe you have a problem with your room ? Are your speakers near the corners or is the listening chair back against the wall ?

I heard the Cremonas powered by the Ayre V-5xe at the Festival Son & Image in Montreal last year, and the sound was fabulous, among the best rooms at the show.

Try either Ayre or Krell.
