Jim, Great review! But now I'm not sure if I will be satisfied with this is board?

Right now I'm just using a Tyros and a classic Motif. Just curious; do you think this would be a significant upgrade to satisfy my need for a better piano sound?

I know sound is subjective, but I always value the opinion of one such as yourself, that has played a much larger variety of keyboards than I have had the opportunity to do.
