Acoustic are inconsistent, to be sure, but they still manage to have the same overall tone(that is if they have been voiced properly).

Yamaha manages consistency without sterility, in my opinion, and every note sounds like was sampled from the same instrument.

We all have a sound in our head that we call "the piano sound" and it surely will differ from one to the other.

That's why these types of discussions rarely solve anything, but they are always interesting, informative and even entertaining, if we don't take them TOO seriously.
