Voltage, maybe, but if you look at the source resistance of a MC, I am
not sure its less "energy".

The stylus on a MC does I suspect have less mass to move.

energy too, but it's not as if your driving your speakers directly.
Fortunately we have an invention called the amplifier.

Yep, you are right, just compaired a Goldring MM and Ortofon MC, MM
about 3.5 times the energy out compaired to the MC.

I'm curious: what unit is that 'energy' measurement? Is it a power
measurement ie: microwatts, etc? I usually think of energy in joules,
power in jules/s or watts. I've never heard of anybody giving a ****
about a cartridges 'energy' measurement; just the voltage output
and recomended load capacitance.

Well, partly I was in pedantic mode with the original comment, but if
(as I do) you use a transformer to step up the voltage of the cartridge,
then it does have some bearing. The load impedance also is important not
just the capacitance. Most MC carts have such low generator resistance
that the capacitance makes little or no difference.

I always kind of assumed that was the reason. But I don't know
enough about such things to be sure.

Why not ask Ortofon or one of the still-extant cartrige manufacturers?

AFAIK Ortofon primarily sells MM cartridges.

Compare

to

Even Ortofon's own technical data favors their MM cartridges

Nope.
