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


Some mighty long discussions on this already here but I need a refresher!
Having decided to upgrage my phono amp to a Dynavector p75 mk3 I am now wondering about my cartridge.
At present I have a Clearaudio Emotion 4 table with a Clearaudio Artist v2 cartridge.
What are main difference between mm and mc that I could expect to actually hear?
And lomc and homc? What is all that about?
Sorry if this has been thrashed to death already but just trying to get a laymans understanding if possible.

If you wait nine more years, you may have had the honor of starting your own 13K-post thread.  Because you have in a way re-stated Raul's question.  You cannot expect others to tell you what cartridge you will like.  Period. That's just for starters.  In addition, your question is based on an assumption that either all MM cartridges can outperform MC ones, or vice-versa.  (Maybe that's an unfair summary of your question, but that is one take-away from it.) That is simply not the case.  There are a few MM cartridges that outperform many or most MC cartridges.  (For a hint of what those cartridges might be, you might just read Raul's initial post on his long thread.) There are also a few MC cartridges that outperform most MM cartridges. It's a mixed bag, and only you can find your way out of it.  If Robjerman's rationale were correct (about MCs being superior because of having lower moving mass), then Moving Iron (MI) cartridges should rule, because MI cartridges have lower moving mass than do MC cartridges.  On top of that they generally have higher signal voltage output which makes the job of the phono stage much easier, in that the phono stage needs to provide much less gain for an MI, and much much less gain for an MM than for any MC.  With gain comes distortion and noise.  (One disadvantage of a LOMC cartridge.) Also, contrary to your assumption, I would argue that very little to nothing has advanced in the area of cartridge design, in the past 9 years since Raul opened his thread.  Certainly there is nothing new in the price range where you seem to want to shop.  So, my opinion is that you need to do some critical listening of your own.  I rank my top MM cartridges (Grace Ruby with Soundsmith CL re-tip, Acutex LPM320, Stanton 981LZS) in the same breath with my best MC cartridges (ZYX UNIverse, Audio Technical AT7, Koetsu Urushi, Ortofon MC2000).  I really have never heard a high output MC in my system that could compete in any way with those listed cartridges.  So, no HOMC for me.

A further thought.  In your price range, which is to say at $600 and below, you might consider the Denon 103 or the Hana SL.  Other than those two, I would suggest an MM or an MI, because there you get more bang for the buck.

Rarely mentioned is the third alternative---Moving Iron, Grado and London (aka Decca) being the two best known. A big advantage of the (generally) high-output MI's is their lack of the need for either a transformer or extra gain. London's produce 5mV output!
Hi guys - check out a website called REGON AUDIO by Robert Everest Greene who has written for THE ABSOLUTE SOUND. He gives a fascinating insight into MM carts. What is interesting, and I have found is the MC's pick up certain artefacts in a recording that when heard in a master tape are never picked up on, but due to the MC design they are. These often give a sense of air and magic that aren't in fact accurate - the MM's were in fact closer to neutral. I have a Pickering XSV4000 and I am impressed with the way it goes about its' business - it doesn't major on 'airy highs' but has an earth driving musicality that none of my 3 MC's deliver. In addition to this they don't require as much amplification as an MC. So MC's give a magic when done correctly, but MM's have their own strengths of equal value. 
Uberwaltz, you’ve received a lot of excellent comments above. I would add that a good means of narrowing the bewildering range of choices you would have in going to an LOMC cartridge would be to choose one having comparable weight and comparable compliance to your present cartridge. In doing so you would minimize the possibility of a mismatch between arm and cartridge, since your present cartridge appears to be commonly supplied with your turntable.

Your present cartridge weighs 8.4 grams. Its compliance doesn’t appear to be specified, but the compliances indicated at vinylengine.com for numerous Clearaudio moving magnet cartridges are all 15 x 10^-6 cm/dyne, presumably at 10 Hz. (Cartridges manufactured in Japan typically have compliances specified at 100 Hz, and to equate those numbers to the 10 Hz specs used by European manufacturers multiply the Japanese numbers by a factor in the area of approximately 1.7, as I understand it).

That would seem to rule out the Denon DL-103 and 103R that were mentioned. Although their weights (8.5 grams) are very close to the weight of your present cartridge, they have 100 Hz compliances of only 5 x 10^-6 cm/dyne.

Also, while I’m not familiar with the phono stage you have purchased, and specifically with its noise performance, keep in mind that choosing a cartridge having a rated output in the area of say 0.5 mv is less likely to result in excessive hiss than one having a considerably lower rated output, such as the DL-103R (0.25 mv). I note that the description of the phono stage recommends a minimum cartridge output rating of 0.15 mv, but I would take that with some grains of salt.  It's usually a good idea to provide significant margin relative to published specs.

Good luck with your choice. Regards,
