Well this definitively proves it!!!!!
The evidence is overwhelming!!

Both keyboards are equally just as good and bad, and both of them cam be made to sound good or bad.

Its really all about the player.
Both boards can make a bad player sound good and a good player can make one or both of them sound bad.

I personally thought that the G70’s rendition sounded better. It had more space and character to it. The balance of the sounds on the G70 sounded more appealing. The G70’s rendition was slower to me and the sound selected on the g70 was more natural sounding and that added to the warmth. I did however like the percussions in the Tyros 2 rendition.

If I were to base a purchasing decision just on those demos alone, I would choose the G70. But I have heard the Tyros 2 on other occasions and I know about its sonic power and greatness. I have also heard the G70 in situations where it just did not sound good.

Give me a Tyros 2 or G70 and I could make both of them sound very good or very bad depending on what day of the week it is.
