Not sure what was wrong with the PA2 you played....Mine has a super Keybed...Fatar and right now I can't remember the model.

Much...much better than the T2 I had for a while (Had them both at the same time) It is semi-weighed and pretty darn quiet.
BUT...I'm not a piano player...soI don't bang down on the keys like Piano players sometimes do...

Everything I have tried has some noise upon release....PA2 is better than most. The key bed is one reason I bought the PA2.
PA800 is softer..it is not semi-weighted I don't think, only played one for a very short demo.

The PA2 keybed is a good compromise betwee piano and organ action.
My 2 cents worth...
