I’m a bit curious as to how many in here has even heard the AUDYA live? I mean in person.
I don’t think its fair to compare these instruments on a couple of bad-recorded demos. The key word here is the LIVE sound, which obviously cannot be experienced through a set of PC speakers.
However I do think that Yamaha sounds exactly the same in live situations as in recordings. This is NOT the case with the AUDYA. In recordings the AUDYA sounds just as bad as the Yamaha keyboards, but LIVE it’s a whole different story – the Yamaha simply does not have a chance in terms of realism and live feeling.

That being said I still prefer Yamaha keyboards since the AUDYA has got the following drawbacks:
A) It is filled with bugs.
B) It cannot play ALL chord progressions.
C) The OS was created by people whom do not give a s… about usability.

These instruments were build for LIVE performances so please don’t compare audio recordings.
