I got a Yamaha U3 silent delivered yesterday. The touch is good, I like the clarity and richness of the sound (compared to my previous piano, an old Rösler), but on lower keys it is very difficult to play quietly (piano, pp, etc) because it seems that either the hammer doesn't reach the strings or it hits them too hard and it is difficult to adjust the touch to the high threshold of producing the sound. However I don't see this to be as much a problem in the higher end of the piano, and I guess this should only develop the sensitivity of my touch. The digital sounds are pretty convincing with earphones, though they tend to scramble when using sostenuto with una corda.
