That may be true ... but I sat down with both of them side by side and I didn't notice the difference...
others can comment on their experience too... both keyboards are 2k -3k price range... not like a 300 dollar psr550! that squeak has.
I tryed the psr2000 and it's action is nothing like the 9000 pro or psr9000.... very cheap.
Sit down and play them side by side ...if you get a chance ...or the other pro's here can add their 2 cents... i gave my pennies worth!
