It could be that he doesn’t have an NV5(S) in stock, and one bird in hand is better than two birds in the air?
Now, let’s assume that his favorite colour is indeed blue (just like yours), and that ‘he’, too, prefers the CA99 over the NV5(S); it is still a bit of a stretch to say that this is shared by professional pianists who compared those instruments; unless he can produce a document proving that ‘all’ professional pianists concurred on the CA99.
And I’m talking about verified signatures of the aforementioned professionals coupled with explicit not implied statements supporting his claim.
Don't want to participate this kind of theories. Only facts - it is official Kawai show room, and they don't sell instruments there, they just show them (all of them including real concert grands). NV5s was there and it was available for test. In that showroom often piano concerts and masterclasses are held, so there are a lot of pianists (including professionals) who test and play on those. So those are sharing their feelings about instruments.
I never mentioned that consultant told that "all" pianists said that, only those who played on those instruments.
Beside this, it doesn't matter - the main idea is that TS can test GF3 with CA99 too if he looking for soundboard + grand piano actions experience.
