I just listened to these demos and wasn't very impressed at all, I don't hear what the big deal is. To be honest they are just ok, but compared to Yamaha top/mid units like my S900 or Tyros 3 the Audya definitly falls a bit short. I can't believe what they are asking for that unit also, not to mention the lack or service & third support in case you need repair also. I would say that the Korg Pa2x, & Roland G70 also are above the Audya in Sound & Styles, support too, but that's my personal opinion. Demos are just that, meant to provoke the customer to buy nothing more. Good luck for those who buy the Audya, hope it works for you. But I would bet trying to sell one and get you money back will definitly be hard to come by. It's just not something that would interest me especially at $4900.00
