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


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.
