Great that you are still enjoying your Audya after all this time Henni - I also still have my Audya (the very first one to come into the country). I did flirt with the SD7, but am too in love with the long Audio loops, low compression, live guitars.
But some do get tempted away or get caught up with 'consumerism' believing newer must be better. Last week we had a customer who bought an Audya when they first came out. He sold that and recently bought a Tyros 5, but after Audya he could not stand the Tyros sound through a big PA system live (although loved it at home) So he bought a 76 key Korg PA4x...just a few weeks later and he is back with us to part exchanged it in for a brand new Audya. Full circle
He brought a friend with him who is a Tyros 5 owner. A lovely chap but obsessed with having the 'most up to date', he kept asking if the Audya we were showing our customer was the latest version and just could not grasp the concept of Ketrons non-cunsumerist approach to their products. The idea that this instrument was exactly the same as a 7 year old model (except for the sound and style updates) was just unnaceptable and he was totally confused
But he was so taken aback with the sound he went home with a new module himself. (the latest version of course...hehe)
