First of all let me thanks all of you for the kindly answers.
@Rod The baby Grand cost $ 3,995.00 and the Concert Grand is $5,500.00
I was not able to listen to the baby grand nor the concert grand, but I listen lots of other models like: Haydn, Haydn SE, Mozart, Mahnler 1.5 and the top of the line The Kiss (Wow!).
They share (more or less) the same family sound.
@JackD201
I fully share your comments. The sound is very relaxed and moreover I like the soundstage that is "not in my face".
The top of the line is the Concert Grand, but as my room side is not so big I think the baby will be the right choice.
@toobluvr
Yes, mee too.
Ciao
