>The Yamaha CF3S (9') does not have a "V-PRO" plate, whereas all the other grands (and uprights) do. My question is: Do those techs servicing CF3S's find the same sound quality being attributed to the plate in both CF3S's and all other Yamaha grands? I already have an opinion, I'm just being curious, I guess. > >Mark Wisner >Yamaha Hi Mark, Personally, I don't hear *any* characteristic sound quality that I can positively attribute to the V-PRO plate, and that was my point. There are way too many other factors that will affect the instrument's voice for me to be able to blame the plate for any single one. If anyone else can hear the difference, I'd sure like to know how they can separate the other design differences from the overall sound and isolate the plate induced difference. That sounds like a pretty handy trick to me, and I'd like to know how it's done. That's why I proposed the little experiment of making sand cast plates and, leaving all other aspects of construction as similar as possible, listening to the difference in sound produced by each type. That should minimize the effects of any construction and design differences except for the plate, so we could find out. Ron N
