Today I encountered a piano with the same problem. The dampers kinda went 
"Doy-ink", the "ink" being the dampers touching the strings.  I needled the 
dampers once and it helped on some felts better than others.  I ended up 
replacing the entire set.  You say that sandpapering was opening a can of 
worms...  In what respect?

I would be interested to hear responses to this post.
