Recent playing around with my AT95e has revealed to me the evils of high inductance in MM cartridges. I've found that it definitely improves in top-end refinement as you reduce the capacitance it 'sees' - a direct result of the 400mH inductance it has, I think. But, certainly in my set-up, getting down to the 100pf total capacitance loading that I think would be ideal is impossible.
But it occurs to me that the reason it has this high inductance in the first place is because of the 'need' to generate several mV of output, as is the MM cartridge norm. So I've been pondering why no cartridge manufacturer has produced a low-output MM cartridge. It would have the same sort of loading and amplification requirements as MC cartridges, and would presumably have the same sonic virtues too? There's surely no intrinsic difference between waggling a coil at a magnet or waggling a magnet at a coil?
It would have the advantage of relative load insensitivity, but could also retain the advantage of having a user-removable/replaceable stylus. And it would presumably be easier, and therefore cheaper, to manufacture than MC designs.
