Thanks to everyone for the advice. Bless this list! By the way, one suggestion that did not appear but which I would like to report is sound-insulating caster cups designed specifically for this purpose (catalog item #341). I first heard of them from Yat-Lam Hong at the last convention. They are made in the U.K. and available through Fletcher & Newman, the British piano supply house. I think I'm going to recommend a set of them and baffles under the soundboard. Thanks for everything. Paul Larudee
