I have -- but, I'm afraid, I never noticed this difference in dynamics between Cremona & Amati... if anything, the Amati would be my choice. However, I wouldn't attribute this to "dynamics" per se but, rather, to a better rendition of scale as in reproduction of a fff.
In how big a room will you be playing these spkrs?
The Amati are "big" and the latest version seem to need even more room than the previous ones...
As to the new Amati vs the old, I haven't compared them side by side unfortunately so, tenpted though I may be to opt for the new, don't give too much credence to my choice.
Last, I find the Cremona a nice product and OK priced (by SF stratospheric standards). The Amati is expensive. By comparison, the Strad -- an interesting implementation -- is not only better but much better value. (IMO, YMMV, etc ad nauseam.)
