I drove 142 mile (round trip) to play Tyros 3 at Sam Ash in the Dolphin Mall in Miami. After playing for 1 ½ hours, using my Bose earphones, here are my thoughts.

None of this is based on dollars.
If you are going from the S900 to the Tyros 3 you will enjoy the keyboard. You will go from a inexpensive feel to a quality feel. (The keys) The over all sound is richer, fuller and to me. The number of styles and instrument sounds are worth the making the change. 2nd party changes are nice but they do not compare.

The Ty3 made me feel like playing, I have not felt like that since my KN7000. I was comfortable with the OTS settings they were more like the intro and style variations. One of my main reasons for upgrading to a TY3 or a TY2 will be because of the screen clarity and size. Yes I can slant my S900 so I can see the screen better but no comparison, the Ty3 is big and beautiful. I am sure that if I went into the deeper part of the Tyros 3 I would have found more reason to want to buy it.

Moving from Ty2 to a Ty3 is another question. More improvements then the styles and instruments would be needed -- I had no time for that.
My opinion, if you are going to stay with Yamaha then step up, grow with the company. (Not taking dollars into account) I was never unhappy when I stepped up, some models improved greater than others but they were all going in a positive direction.

I played the Roland top of the line and a korg e60 (I think). What has been said on the forum about the sound being in your face is true – My ears told me, you know the way I hear it, that they sounded more like a live band, but I felt the Band needed some improvement. I hope that does not make anyone unhappy.

In time I will buy a Ty3 when the frenzy is over, John C.
