Whats the difference. It won't make anyone sound any better unless you increase your playing skills thru practicing and experience. It's the "Musician" that makes the Music sound great not technology of the keyboard. I know so many people who tell me they have the latest and greatest KB's....but lack the talent to play them proficiently, because they were lured into buying them on "FEATURES" alone by some salesman who just cares about $MONEY$ and you get stuck with a unit you'll never learn in a Thousand years, it's sad. A good mucian can make an EMINEE Organ sound good ....
if you get my drift?
