I believe that the MC/micro-line profile change is a large part of the improvement coupled with the synergy of the arm/table/cart/phonostage (Ittok/lp12/MC X30/linto).
It is interesting how different the sound of the chain of components can be when creating a similar level of performance. As you stated "Not Better Not Worse" just different. My rig now has a classic old school vibe of being (LP12) warm but is now so deep, detailed, and satisfying.
