Aside from the Audya having the best live sound, with Korg probably second, one has to go into it a bit to fully appreciate it's features. Some say that it falls behind in lead sounds; maybe, but when taken as a whole, with it's super effects, it beats the other 20 or so keyboards I have had. With AJ's upgrade,it just got better.
I am sure the newer batches of Audya are more bug free than some originals, and this hurt their reputation, along with meager support and marketing. I was lucky-never a problem.
OTH, I still prefer My KN7000, S910, or vArranger for more subdued dinners or NH venues.
