I think the original Cremona without a sub sounds better than the Elipsa. For me, the original Cremona has the traditional full, round SF sound (even though some say it is colored) whereas the Elipsa has the new flatter, more detailed sound. Really depends on what style you like.
I currently have Cremona and love the Strad so was very ready to upgrade to the Elipsa, thinking it was a scaled down Strad. But with the new sound, I just kept my original Cremona.
I cannot compare the Cremona M with a sub and the Elipsa, since I do not like the sound of either. Lots of people like the new sound. Maybe they can comment.
