I was deciding between C4 and Amati 5 months ago, went with Amati at the end. I have been a loyal Dynaudio customer (SF Electa Amator, Extrema, Merlin VSM, Dynaudio Confidence 5, and some others), but found the new C4's look to be too domestic unfriendly. C4 also does not have the bass rhythm and tonality of Amati, but I do think C4 is slightly more detailed and sounds more realistic. Both will play loud, both will be good investment for the next 10 years, and both will please their owners with fine music.
Dynaudio is not known for musical sound where Sonus Faber is usually some what "colored". I find Dynaudio to reproduce piano better than anything out there, even ribbon or electrostatic can't compete in this regard. But Sonus Faber has that magical ease when reproducing strings and voices. I am not into rock, so I can't comment on that.
Buy the one that makes you feel your money is well spend. I chose Amati because it makes my wife and me happy. Making myself happy is easy, but making both of us happy takes a lot more than just another good sounding box.
