Vimberg Speakers

Hi Guys,

Anybody owns Vimberg speakers?
Have you compared the normal version to the D version? (Diamond tweeter)
What were your listening impressions?
What do you drive them with? Are they difficult to drive being 4 Ohms?
Anyone heard them with the constellations Mono 1.0?
Are they difficult to place in the room?
Are they versatile speakers?

I'm going to rebuild a system from scratch and I'm interested in the Mino.
I don't want to spend more on power than on the speakers (ie too difficult to drive)

Any insight is appreciated,

Thanks
