As always Mikem, we appreciate your diligence in finding pretty decent arranger demos.
This, unfortunately is not one of them. Both instruments being recorded with the camera mic...along with volume discrepancies and style variations makes it difficult to distinguish any real quality of either keyboard.
I personally have had the pa600 and now the 970. The Live drums and the amazing electric guitars on the 970 kick the 600 right out the door. I know the pa900 probably sounds better than the pa600...and it also has a great vocal harmonizer, but I don't think the 900 is ultimately going to stand up to the sound of the 970 (IMHO).
With that said...don't allow this demo to persuade the purchase of either keyboard.
This guy is a pretty good player as I've heard him on other demos. But on this demo...he ain't cutin' it.

You're welcome, Jingleman.
I'm sorry you don't like this particular demo. It's not the best demo, I know, but there have been very few demos demonstrating both keyboards, so I thought it would be worth a look.
I agree that the PA900 is no match for the new S970.
Like I've always said, the best demo is when you actually go to a store and try them out yourself.
