MC or MM?

In a MM(moving magnet) cartridge, the coils are in the cartridge body and the magnets are on the end of the cantilever, moving around. In a MC(moving coil) cartridge, the coils are on the end of the cantilever, and the magnets are in the cartridge body.

Generally speaking, in low output MC cartridges, the moving mass is less and the ability to move quickly and respond to low level detail is better. Also, higher gain phono stage is required.

It will also help to know what your system is. Advice will mean a lot more. Someone has probably had or tried what you have, so, let us know, and we'll see who can help.

This is what I will be using
Clearaudio EMOTION TURNTABLE W/SATISFY ARM

so want to add either a Grado Reference(MC) or Grado Statement(MM).

Music is: 40% Jazz, 40% Classical, 20% Opera

Techno, I would imagine that would be a great combination with a Grado MC. Probably very detailed sonically. The sonic characteristics of the Grado in conjunction with the Clearaudio could end up being a very neutral combination.

That is what sucks about turntables. You can only assume what a combination will sound like until you actually hear it synergistically. The Clearaudio arm and bearing structure is extremely rigid. It theoretically will make the most of either of those Grados.

Best of luck., Ed

None of the Grados are MCs. But many models come in different sensitivities (e.g., the Reference) and some of these sensitivities are down in what's usually considered the MC range. Confusing? Not as much as their nomenclature :-)
