My car always drives better when I've washed it.

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)
