Clavinet C compared to D6

[mvanmanen]

Is there a significant difference in sound between a Clavinet C and D6 if both have the same strings? Is one considered of higher value?
I recognize that the D6 has the additional toggle switches.

thanks for your expertise,
Michael

P.S. I just have finished disassembling my D6 down to the case cleaning the parts along the way. The tolex arrived in the mail today so am hoping I can post some pictures soon.

I think the "C" would have more value to someone looking to complete an early Stevie Wonder or prog rock keyboard set-up.
doesn't have the tonal versatility (not that you'd really need it, still sounds like a clavinet. none of the audience would notice, and only a very few clavinet fanatics) of the D6, and doesn't have a mute slider either, although I think you could retrofit one if you wanted.
make sure you take plenty of pics of your project, I'd love to see them.
I have a clavinet/pianet Duo, and I just got a D6 that's probably going to get a Castlebar installed, as soon as I save up for it.
