Hi Lithojoe,
I personally don't know of many MM designs that have sound comparable to, or better than, good MC cartridges. Most MM cartridges sound muddy, opaque and lacking in microdynamics. The one notable exception is the Decca London Reference, and it has its own set of problems (not a great tracker, high tracking force required, etc.).
As to a new phono stage, I don't see how a phono stage can compensate for what is lost from MM cartridges.
