I've played a few Fazioli albeit briefly. New 212 & 183, and used 228(for hire), 212 & 183.
The first thing I'd say is the action/touch on all of these was lightish, but very very nice; according to Fine it's Renner, but each top maker does it's own thing to whatever Renner they buy in and it's noticable. Made me feel I could play faster.
Timbre of the instruments, I liked the bass and tenor a lot (which seemed almost reserved but profound at the same time), but the higher treble is a bit shrill, and the top octave like icicles breaking, reminded me a little of Bechstein D280's but intensely so.
As for the cabinets, the finish is excellent. The inside of the new 212 was birds-eye-maple wood (Stuart & Sons would have put it somewhere on the outside).
The used models had mellowed, but that top octave or so still did not appeal to me, and honestly, I wouldn't have bought any of them.
Regards
Andy
