old jmw9 vs new


I am just curious if anyone else has had a direct comparison.  It seems to me that the new jmw 9 does track better but does sound different to me.

I too am interested if it is really an improvement to go from the original JMW9 to the newer stainless version. What are the differences?
l have the original Scout. The only sensible way to go to a 3D arm would be to trade up to a Prime. Don't have that as an option. 
Why make such a little improvement, when you could take a giant step up with the 3D arm if you can mount it on your turntable (you don't say what table you have)
How does it sound different? Did you ever get any input on your ? From other sources than goners?
