Hi Derschoenebahnh,Thanks for sharing that!One possibility could be to install N.Y. Steinway hammers on your piano.The instrument in the link here, though made up to a point in Asia, has N.Y. hammers . . .A set of N.Y. D hammers/shanks costs around $1000. I am not sure about cost of the hammers for the other lines.Mvh,Michael
Only thing, the piano is only 1.5 years old. I bet $1000 would just cover the hammers and not labor costs. I hear Abel hammers are pretty good too, but either way, an expensive fix.CG
