FransN,
I too have a PA600 on order but we have not gotten them yet in the US. So far I like the S950. It reminds me a lot of my PSR3000 in terms of operation and layout. I got a chance to do a side-by-side comparison of my Tyros 4 today and the S950 holds it own in an unexpected way. I am working on getting some recordings of both to post but right now I have little time so it will be next week before that happens.

Please let us know what you think of the PA600. I can't wait to get mine. I have the Korg MicroArranger and just love it.
