Personally for me, it comes down to just one simple thing.
THE SOUND! That LIVE BAND SOUND.
I have a Tyros 3 with me on stage also. However I find myself using the Audya about 75% of the time.
Like many, I've had and am having issues with the Audya. Still, I just love playing it.
Never before have I been able to offer this kind of sound on stage.
