I will say that I have 2 Petrof grands in my client list that are just a joy to tune and play... Both responded to voicing well after a number of years of play.

I've never played a Shigeru Kawai, maybe I'll have the chance to some day.

Ron, you might remember (or I posted it above, don't recall) that my current piano is a Petrof upright. It's one of the "European" style uprights (what I can legless). I really like it's sound, not that that is relevant to a Petrof grand. But if I have the opportunity to play a Petrof grand, I certainly will!
