I just listened and I have to say that I think the Audya is not just a little better, but much better.

And I say that as an owner of a Pa2x.

The piano and sax were definitely better; I'm surprised that's even up for debate.

And as an owner of the Pa2x I can tell you that the Bigband comparison is flawed, because they used a demo instead of showing what YOU can do. You can definitely NOT do that on a Pa2x...

I also own a Yamaha Tyros 3 which has its advantages and disadvantages. Unfortunately it doesn't measure up to ether the Korg or Audya when it comes to drum and bass sounds ....

Very sad since right now it's my main gigging kb.
