Hi Pete
I just purchased the Audya 5 in Sydney not that long ago, yes marketing is poor as before then I've never heard of Audya.. As for support..well the gentleman basically boxed the arranger and shipped it to me, but with anything in 2013, you now have the Internet at your fingertips so its wise to do your own research and here you have both lovers and haters, however you should have quite a clear understand whether the product is right for Your usage.
The 2013 Audya right at this moment works flawlessly, I'm not a tech mech.. So I don't dig deep enough maybe to discover any potential problems, I just enjoy the keyboard the way its made and enjoyed its world class Audio Styles.. Only listened to be believed..that's why I bought it and loved it for that purpose,. With Ajamsonic and further developments to enhance Audya, I believe it will only get better and that alone is a very exciting thought..
As for after purchase support.. Well you've found your way here, and believe you me, hold on to your warrantee.. Thrash the living daylights out of her, post your questions and curiosities here and get all the answers you need.. Thrash more music out of her and when she starts smoking.. Then contact the guy that send it to you..
Hope it helps..
Regards Ky.
