If this recording is in indeed genuine, then I find the prospect of the carbon-fiber soundboard very exciting … along with whatever else has gone into this instrument. It has the the most Steinway like complexity that I’ve heard.
While in many ways I would prefer the Steinway demonstrated here, as a tech, I have to stand behind Yamaha as a marvelous instrument too!
