Interesting...I have heard both but not in the same system or at the same time. I would say they are certainly both competitors and are comparable in quality. This is more about system and personal preference. What i would NOT say is that if you could "only" buy the Amati that you should feel disappointed that you could not hear the Hansen Prince. They are both good speakers at about a comparable level. I personally would prefer the Amati...and that is partly because i am a big SF fan having owned by Guarneri original and SF Strad at one time, but i know of others who would say the opposite.
And what did you think about the Hansen Prince? Could you describe them?
I know well the Amati Futura, I have some friends here in Brazil that have them. In one of the systems they are with AR CD8, Burmester 808 MK V and MC601 monos (and Siltech cables); and the other system are with MCD500, C1000 and MC601 monos (and cables WireWorld).
Your impressions about this speakers is very important!
