Old thread, but there isn't much info out there from regular owners so I thought I'd offer my experience FWIW.
I bought a VV64 Deluxe used, but it was basically unplayed. The original buyer had to flip it for financial reasons. For reference, my other rhodes are Mark V's and a Mark I.
My main takeaways so far:
-the VV is ridiculously light and portable. not just a little better like the 54's and the Mark V's. way way better. like, carry it under one arm with something in the other hand, better. for some gigs that might make the difference in whether i would bring a EP or something like a Nord.
-the action is excellent. nothing at all like the Mark I (mine is pretty much stock, and very spongy). the VV is super fast and snappy, with a very defined stop at the bottom of the key travel. it feels like the overall key travel is shorter than the mark V's, though I haven't measured. i'm pretty used to the mark V as my reference for good rhodes action, so i wouldn't necessarily say the VV is "better", but it's certainly not worse. excellent, but a different feel.
-very clean sound (little/no hum)
-i had a bad pickup when i opened it. maybe that was just a fluke or it happened during shipping. but i've had a lot of rhodes shipped to me and never had one arrive with a broken pickup. again could be a fluke, and VV sent me a replacement very quickly. it was easy to install and has been fine since.
-the sound is a little tamer than my mark V's. when i just play it by itself, it sounds beautiful and I have no complaints. but when i've had it side by side with the mark V's, the VV's high end seems almost dull by comparison. I spent a little time trying some different pickup placements and adjustments to the tines but couldn't capture that extreme clarity I get from the V's. but that's not to say it might not be possible. and again, when i just sit down and play it i never feel like it is lacking anything at all. so it's very much a taste thing.
-i'm interested to see how it holds up physically. i'm pretty careful with my gear. other than the pickup it has been fine. but there's that ironic suspicion of whether something so much lighter will hold up as well.
-i wish the lid were flat, as (just like the mark I's) it makes putting other boards/effects/etc on top tricky. maybe they make a flat option? i've seen some comments about the lids not holding as much weight as the rhodes (introducing buzz on keys), and the VV material does seem to have more give. i usually stack a D6 on my rhodes without any issues, but i'm not sure i'd be comfortable doing that with the VV. but lighter stuff seems fine.
Finally, FWIW, here is a recent set where i used the VV. it's a more experimental set overall, but there is some cleaner playing in the middle and towards the end
