What is the preferred cartrige mm or mc and why


Curious to know why some audiophiles prefer a moving coil cartridge over moving magnet type. What determines this preference? Does the tonearm determine which type is preferred? Why?

The fact that your cartridge is an MC does not make it superior to MM cartridge (or Moving Iron, Moving Flux etc). It's been said many times and approved by many audiophiles worldwide, not by those people who's buying cartridge by reviews or stereophile top 100 recommendation, but those who dig deeper and really understand the process and testing different cartridges in their systems. This is the ONLY way find what's the best.   

I use both MC and MM, practically i prefer MM cartridges, the best MM cartridges are vintage MM cartridges and they are much cheaper than very bad MC cartridges and probably 10 times cheaper than some good modern MC. But the cost is no object in this experiment, it's fact that decent MM could the the last cartridge, no need to search or pay more for an MC. In most cases the cost of MC phono stage or SUT or MM phono stage +SUT or MM phono stage +HEADAMP is a pain in the ass when it comes to LOMC. Then add re-tipping process and so on. 

The MM/MI/MF has replacement styli, relatively high output, they are neutrial, they are cheaper, they are amazing if you know which one to buy. 

Some reasonably priced vintage MC cartridges are good, but people are crazy when they are buying $3000-8000 MC cartridges without having a chance to audition a decent $700-1200 MM from the 70s/80s in perfect condition.     
Here's an article that seems about right i.e. from what I have read on this topic at other sites

I currently have Moving Coil, but there are some compelling arguments for the alternate technologies

On the fence - Steve

I have never seen Tyrolean pants anywhere else than in Germany

and Switzerland. So, obviously, those pants never become

''universal fashion''.  The MM fashion was universal till the 80is.

Then the first Supex 900 MC become the fashion. Those who

owned or , goddammit, bought MM kinds become the losers or,

to use the former qualification, Tyrolean pants bearer in the universe

of , say, jeans? Can anybody imagine seducing a girl with Tyrolean

pants on? Then, like with cars, the more expensive the more

impressive. Not to stay behind I (also?) own more MC kinds.

More to the point I want to show that I can afford MC kinds(grin).

Just when you thought the world couldn’t  get any dumber, it proves you wrong.

Bsme85, I am doing my homework, assignment is to research the OP subject matter. Can't think of a better way than going to the end user for their views.
