Henni,
I was once told (actually many times) DO NOT LISTEN to the demonstrator...listen to the instrument. That was back when I was buying $12,000 Yamaha HS series organs.
Still applies today...you don't get to take home the demo guy/gal, only the instrument.

Better yet, play it yourself!
Soon we will al get to play Audya, then we decide how it is.

But, I agree the Yamaha demo folks are top notch.
