Not exactly. By several accounts, the early Silbermann prototypes were almost unplayable. Bach criticized the action and the sound of the upper register - but later, he even became a sales agent for Silbermann. In the latter part of his life, he always kept a couple of pianos in his house.
Hahaha
My Behringer model d was broken, I sent it for repairs, got a broken unit back, which again I had to sent for repair (that is their procedure). So it is gone since beginning of April. I think I will hold back on the behringer units...:
