Age old discussion I know but MM or MC? Benefits?

Raul who started this thread never stated that MM kind is/was better then MC kinds. His primary thesis was that MM carts are an good alternative which was forgotten because of the MC domination. But the most of us have seen this as ''MM contra-revolution''. Not to stay behind I bought each ''cart of the month'' that I could get. But I prefered all this time MC kinds.There is nothing rational in our hobby
you know (grin).

"  are mc carts something I should even care about? "

you wont know until you try one.     

obviously it has your interest or you wouldnt have started this thread about it.

I agree with addy - no matter what anyone tells you, you won't know if changing to an MC will be an improvement for you until you try it. 
It may mean something to you, it may not. My guess is - it will not. 

And these are exactly the real world thoughts I am looking for.
Yes it has my interest mainly because we all feel the need to upgrade and change to try and find that improvement in sq that gives us a feeling of great satisfaction and a job well done....lol.
But also I have "upgraded" many times only to feel I took 3 steps backwards!
Are my table,arm and phono amp up to the task of revealing and sq improvement from a mc cart to begin with.
And what sort of price range and type should I be looking at?
Mostly rock music,modern and classic rock.
Definitely no jazz or classical here

The mc type of cartridge is inherently faster and able to trace more accurately the vinyl grooves. Lower moving mass, lower inductance and lower noise compared to mm types. Read Mitchell Cotter's explanation in The Audio Critic circa 1977! And he made excellent SUT's and IC's (Verion Triaxial's) - both of which I've owned! For the money the venerable ,(1962!) Denon 103 mc cartridge can't be beat! I first heard it in '77 mounted in a Denon 307 arm on a TOTL Denon DD table. Step up device was a Levinson JC-1 clone. Sound quality was to-die-for! To this day I still prefer and use Denon 103's, 103R's, 103 Gold Anniversary, 301's and 304's.
