I'm a little suprised no-one has brought up the following with regard to your initial post:
You didn't audition the Sonus Faber Maxima Amator speakers at the dealership. You audition a system incorporating the SFMAs. In order to re-create what you heard at the dealer it would be necessary to possess either the same complete system or something similar.
One never listens to loudspeakers in siolation. Only ever to complete systems. Include the room and room positions for the speakers also.
It might be possible to buy drivers and diy approximately the SFMAs. Is your system equivalent to the system you audtioned them on by any chance?
