Grado new v2 cartridges?

I certainly would think they are better or just different in some respect.....can't think of a manufacturer willing to offer an inferior product. I would call Grado and ask them the difference between the 2 cartridges.  No one would know better than they.

I have a V2 Reference Sonata and though I never owned or heard a V1, it sure sounds good. One of my favorite of several MM carts.
