Got a chance to play two different Clavinovas today; a 601B and a 705B.
Keybed wise they both seemed to play a bit better than my DGX650 but I couldn't tell a huge difference in touch from my DGX. Of course, I'm no expert.
Arranger wise, I didn't think they were any better than a basic Yamaha arranger. Not impressed at all in this regard.
Sound wise was another disappointment. I think the sound system in my DGX is as good as either Clavinova.
And again, I'm no expert, but I couldn't tell a huge difference in piano sound..Clavinova vs my DGX.
I may try to play a 609 or 709 if one becomes available.
I came away thinking Clavinova = lots of $$$ for little improvement over my DGX.
