Hi Larry!!
Yes, assuming equal flat EQ recording for both keyboards
I had a PSR3000 too. This one was the worst if you play with other musicians.

My last Korg keyboard was a Trinity. It sounded amazing live and in recordings but the touch panel was so temperamental that it couldnīt be used safely live and Iīm still reluctant of using touch panels but, the PA600 seems a good compromise...
I will purchase one as soon as it is available in southern Europe.
Regards
Jo
