Comments on the Sonus Faber Grand Piano

Any comments on the Sonus Faber Grand Piano Speakers to work in my living room with the BAT VK-D5 CD Player and Bow Wazoo Integrated amp? During my first test listen, I found them very open, musical and they seem to just let the music flow. Base response was acceptable but not down to the lowest of notes. I am going back for another listen and am asking for more opinions. Budget is $4K (but can go to $5K). Speaker size is very important for my wife and sound quality for me. thanks...
