I am not sure there is a debate to be had here. About ten years ago Sonus Faber changed there sound by adding detail / increasing the treble energy of pretty much all models. The strong, natural mid-range bloom and nuanced bass was supplemented with a more balance treble. Since then all models have a very similar Sonus Faber natural musical sound… with better dynamics and bass depending on the model, with imaging and sound staging also influenced by model and form.
I have owned Cremona (pre-tonal change), Olympica 3, and now Amati Traditional. I have spent a good deal of time listening to Olympica Nova, Lilium, and a couple other models.
