Marten Duke 2 anyone own or heard these?

I heard the Duke 2's at the last Newport Beach Stereo Show
and fell in love with the transparency. Any Audiogon members
have or know the voicing of these speakers? I have full range speakers but I'm looking for a bookshelf that is fast but smooth. Not bright and no sibilance with female vocals.
I was looking at the Harbeth 30.1s which I know are smooth but I was really impressed with the Duke 2's at the show.
No local dealers so I cannot audition.
Any comments would be appreciated.

Thanks Ron
