Grado MI windings...

While moving iron designs differ from moving coil, it is interesting to see what Grado says the difference is between their HOMI and their LOMI:

"The Reference series cartridges have a total of 6,000 turns of wire on the coils. The Statement series has a total of 380 turns. Since we have considerably fewer turns in the Statement series, we can use a much larger size wire. This new wire has over 16 times more area for carrying the signal; it also lowers the resistance from 470 ohms in the Reference series to 2 ohms in the Statement series. Fewer turns of wire on the coils shortens the distance the signal must travel from 125 feet to a little more than 7 feet. In the Statement series we have also shortened the magnetic generating gap in the stylus, increasing the flux density."
