there was any

it a bit
more & the sustain though slight increased on a few notes =

,thru D sharp 6. It was so slight that I cant imagine a beam and =

wouldn't have the same effect. For all its touted features
I'm questioning its benefits not to mention the torque it puts on =
the rim
where some separation is often seen. Know what I
mean? </FONT></DIV>

slight to almost non-existent in some pianos. In others it's a bit more =
obvious.
It depends, I think, on the actual characteristics of the individual =
casting.
And, yes, the same result can be obtained through the use of a beam and
bolt.</FONT></DIV>
