I’ve got an old Chickering upright which is tuned to A 435 or so and a wonderful bass. Comparing an upright’s sound to a grand or baby grand piano is not a fair comparison. Because of the hammer action, an upright is not in the same league as a grand for sound or for ease of playing. An upright hammer has to work around gravity while a grand uses gravity. Different animals entirely.
Otherwise, good video. I can hear the difference between each of the pianos and wish I had the space and the money to afford a concert grand piano.
