Julie: The big problem I have had with Petrof is the setup of the actions. All kinds of problems with excessive touchweight due to heavy hammers, improper use of lead, key ratio and parts alignment problems. These problems can and do occur when Petrof uses anyone's actions. Renner builds the parts, but Petrof is responsible for the proper setup of the parts. One incredible sounding Petrof I serviced used wippen helper springs in the bass, and lead in the treble! Had about an 80 gram downweight when I found it....Petrof's high strikeweight is overkill. If you want the piano for a large hall and like the big sound, be sure it does not have 80 grams downweight first. You can only fix so much with "balance weight." If the Petrof dealer is aware of these problems and makes sure they are corrected, the piano can be wonderful. I always tell my clients to make sure the tech checks out the piano - especially the action - first. Sometimes pianists are so enamored with the sound that they overlook the cumbersomeness of the action - until they have bought the piano.
