They both have nude diamond styli, rather than the VMS10's bushed elliptical, giving lower moving-mass. The 20E is an elliptical, while the 30 is a "Fineline" line-contact type.
The only problem with them is that they are much higher compliance, if my experience with the VMS20E is any guide. This means a low-mass arm is really a necessity, at least for that model.
