</DIV> <DIV> </DIV> <DIV> Are you referring to the front =
or rear duplexes? I know you've studied this a fair bit but I think after=
hearing Ron o. ,Ron, N. , Del, John Hartman and others I belie=
ve there is enough evidence that the front duplex being tuned is a d=
etriment to sustain. The sympathetically vibrating string segment at=
the front duplex is largely responsible for drawing energy from the vibr=
ating segment ,reducing sustain/power and creating more buzzing tha=
n pianists can tolerate. This segment would benefit greatly fom being det=
uned. I've noticed than in Mason BB's from different era's the fro=
nt duplex went from being in a tuned configuration to on of equal length =
string lengths in the front duplex. In the latter the tone is cleaner wit=
h no buzzing and excellent sustain characteristics.</DIV> <DIV> &nbs=
p; As to the rear duplexes having a significant effect on tone ,at least =
for me the jury is still out. If all other aspects of the pianos tone pro=
ducing system are set up well the overall increase in performance t=
o me is not enhanced significantly. However as has been discussed at leng=
th on list has been the detriment of too short of a back scale choking /r=
estricting bridge movement thus tone quality ,power etc. Convince me othe=
rwise. I'm open minded.</DIV> <DIV> </DIV> <DIV> R=
