Well, my original note mentioning that there was damper work to do was where the problem was. A little hint, when I returned two days later, there was only one center unison standing out as problematic. Timing was quite late. Fixed damper timing and everything sounded better. Hammers weren't cupped. As for voicing, they sound good barely played. A little more playing-in and I can evaluate if I want a little more edge in the low bass and on the top three to five treble notes. Perhaps a little burnishing with some high grit paper or maybe a little acetone to compact the fibers a little if that isn't enough. Might be a little needling in the midrange after some playing-in. This piano has an unusually long back-scale all the way up into the high treble. Sustain is really good up to the top. This is a player grand that has sostuneto (tabs are not hinged) & una corda shift pedal as well as a player activated hammer lift rail. All in all, quite interesting. The keyframe is flat on the bottom with glide studs in the middle and it does need bedding. I'm thinking of getting out my portable planer an leaving a 1" wide lip on the front rail and the back rail to make this more reasonable to bed. Does that raise any alarm bells?
