Can anyone tell me if it's really true that the Tyros 2 sounds much better than the original Tyros (which I have and am happy with). If it is true, in what way does it sound better?

Thank you, Arie.

HI ARIA,
Welcome to our Tyros 2 club
I have only had the Yam 9000 prior to this Ty 2 so don't have your answer. I can say it is a world better then the 9000.
Tom Tom has the ty 1 and has the Ty 2 coming so he will soon be able to answer your querry.
Scott Yee currently has both and could but he is sick with the flu right now, so you have to wait for him.
I am sure there are others too, that will post here so keep checking back,
Best to you,
Bebop
