Buchardt S400 Special Edition speakers -- any impressions?

I have been a devotee of Spatial Audio speakers for several years, thinking I would never move on from them. However, I heard these speakers in a system with a great front end last year and was blown way with the tonality and detailed soundstage they presented.  I got a pair a week ago and they are really excellent speaker for $2700.  They clearly go deeper in the LF than my Spatials and have a tremendous soundstage, with pinpoint accuracy of the instruments.  They perform similar to the Dynaudio C-1 Contour and Joseph Audio Pulsars for a fraction of their cost. 

I'd be keen to see if anyone else has any experience with them.
