The 1027 Be or Diva will require a high-quality 200-wpc Amplifier to sound their best. Forget the specs., these Speakers are not that easy to drive. I've audition the 1027 Be on Krell, Mark Levinson and Classe systems and they sounded great. 90+% of the Altos. The 1037 Be is now available in the US. I believe it retails for $10.5K, you might want to look into this Model as well.
