Sonus Faber Concerto & Concertino

I know these are no longer in production and that there are two versions, the most recent being the Home. Can anyone who does or has owned them give me general impressions? How about specific differences btw the two versions? How easy are they to drive? If you sold them, what did you get that you like better?

Also, it'd be interesting to explain what kind of presentation you seek - "musical" or "accurate"? And, anybody buy Sonus Faber based pretty much on looks? I'm almost willing to at this point, along with Opera.
