I have not heard the Paradisea, sorry. I bought the Havana, the next up in the line, on recommendation and was never dissapointed. The Bel Canto is more dynamic than the Havana was, but I am not sure it was necessiarily better. Havana was a bit warmer, but the did not extend to either the bass or upper end as well as the Bel Canto does.
Good luck!!
