If I had the BUCKS and was going to buy the next arranger, hands down without a doubt the KETRON AUDYA, and I guess you want to know why? This is my opinion, biggest factors in the purchase would be the sound, the live drums and guitar blow away anything out there, then you have innovation, actually playing a song and never sounding the same each time you play it,these two features alone would sway be more on this board, but then some one else would disagree totally, either way they are both good keyboards.
