I agree the Tyros 4 is a beauty; it offers perfection. The Pa3x offers its own beauty; the ability to make it whatever you want, and that is another type of perfection. Tyros4 does it all for you, but if you are not into the CD perfection in sound then and want a real band sound then the choice would be the Pa3x.
I think it is fantastic that we do have a choice of two great keyboards each offering their own perfection.
