My car always drives better when I've washed it.
Same with any addition to hifi/camera /computer imho
Regarding Fazioli pianos v Steinways I asked the opinion of the piano tuner at the Cheltenham Music Festival (they have 1 Faz,3 Steinway D's).
He said it was too soon to tell (its 18 months old)
However he did say the life of a concert Steinway D was just 10 yrs (all that transportation and pounding performance)
I just stumbled across while searching for another post. A friend of mine sells various brands of pianos, owns his own piano store, has been a piano tuner for years and his favorite is Bluthner. He indicated that Fazioli, Steinway, Boesendorfer, etc. are all very nice pianos, all have their own distinct sound, but his preference for classical would be Bluthner. He had mentioned the Boesendorfer just got bought out by Yamaha and he's not convinced it was for the better. Once you get into that high end concert grand piano for $120K+, it almost doesn't matter, it's what you like. I grew up around a piano teacher at a local college and she had two old Steinways at her home she would teach on and she mentioned that the older models before a certain time period (I forget the date), were the ones she thought were better. Again, it's all what the artist prefers.
