On a related note: today I installed all the 8 upgraded Rhodes models in my Nord Stage. These are the biggest version with most velocity layers. It just so happens that the amazing Swedish rhodestech who have prepared all Clavias sampled Rhodes and wurlys, also have done the work on my 1971 Stage Mark I 88 which I later upgraded with The Vintage Vibe Stereo preamp.
Today I played them side by side for the first time and the Nord has nothing on the real thing. Its hard to describe, but the dynamics is probably the biggest difference. It just plays and answers like a real instrument, and even the sampled pianos with lots of bark (like the amped one, no 7) just feels flat when comparing to the real thing. I really didnt expect the difference to be that big.
That being said, I didnt gig with my Rhodes, or my new Wurlitzer 140B, unless its something extremely specific that requires the real deal. Nord works great, and theres lots of sonic possibilities with different pianos and fix, but a real Rhodes in good/great condition beats it with ease.
