I have an Audya76, but essentially the same.

I have owned every major brand, and find my Audya to be far and away the best sounding. The OS is much easier to grasp than Kurzweil and Korg. The keybed is very good for me, second only to the G70. The styles are very good, plentiful, and fully editable.

In this area, the G70 was a little easier, but not as difficult as the Korg and Kurzweil. I must admit that they might be more editable if one can grasp their difficult OS.

I have never had a problem with my Audya, and have taken on hundreds of gigs.
