I cannot respond as to the other two speakers - but I just purchased the Sonus Faber Conserto Grand Piano. This is different from the Home and ( I think )is not made any more. After the set up I was enthralled. My old speakers are the Thiel CS 2.2 which I liked but could never make work in my room as to soundstage and imaging. These speakers are smaller in size and only a two way design - I was worried as to the bass - well I was delighted with the low end as much as the upper end octaves. Part of the problem with the Thiels is my room - They want more space. So with the the SFGP's I now have the sound I want - As for your taste in classical - this speaker is very neutral - from what I understand the SF Home is geared more towards home theater. If you could audition the Concerto Grand Piano, you probably will hear a difference. Since I have not listened to your other speakers - I cannot comment - but I am happy with my pair.
Good luck -
