I am all for refelting the hammers, but these still have some life in them. They just need voicing. One thing about refelting is that it changes the weight of each hammer, which in turn requires adjustment of the other weights and resistances in the action to obtain a smooth front weight to touch weight ratio up and down the keyboard (I always get all those concepts confused, but when it is done right there is consistent (and very little) inertia in the keys and the overall action feels quite even).
I like light actions. I feel one can play pianissimo faster and I don't have a problem with the singing tone being something you can achieve at mezzoforte instead of forte (which I feel is the case with Steinway, hence my prejudice that they are a little monochromatic).
As for the prelude, that idea sounds kitsch to me, but that's the beauty of art: if you like it and truly believe it, then it is right (and there are infinite ways of playing it right).
Cheers!
