Kevin,<br>
<x-tab> </x-tab>Thanks for
responding. I'm thinking about pounding this one into submission even
though I've never had to do that before for a stable tuning. I take some
comfort in the fact that the dealers' tech had trouble too so it's not
just me. BTW, the dealers tech was able to produce a very stable result
where the piano sat for 6 months on the dealers floor. The trouble only
began with tuning stability (unisons only) and the lack of singing tone 3
days or so after delivery.<br>
<x-tab> </x-tab>I do have
several sets of good ear plugs that I never leave home without. I'm still
wondering, though, why the staple seemed to produce a positive result.
Could the strings being out of phase without the staple cancel each other
out slightly and produce that effect?<br><br>

concerning the stability of the unisons, this one is new, in a new
environment, and it's probably just settling. You are aware that you'll
probably have to beat this one into submission on your next tuning,
though. The end sections are going to need to be stabilized to the rest
of the string lengths, that's probably all it is. You know that Franz
Mohr always said that you have to pound a piano to get a stable tuning,
don't you? Do you have ear-plugs?<br>

<font face="arial" size=2>P.S. I'm not going to address the issue of the
"staples", as I have no experience with them. You mentioned
that there are no false beats, so I don't think that it's loose bridge
pins.<br>
