MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY?


Dear friends:The main subject of this thread is start a dialogue to find out the way we almost all think or be sure about the thread question :  " true " answer.

 

Many years ago I started the long Agon MM thread where several audiophiles/Agoners and from other audio net forums participated to confirm or to discover the MM/MI/IM/MF/HOMC world and many of us, me including, was and still are" surprised for what we found out in that " new " cartridge world that as today is dominated by the LOMC cartridges.

 

Through that long thread I posted several times the superiority of the MM/types of cartridges over the LOMC ones even that I owned top LOMC cartridge samples to compare with and I remember very clearly that I posted that the MM and the like cartridges had lower distortion levels and better frequency range quality performance than the LOMC cartridges.

 

In those times j.carr ( Lyra designer ) was very active in Agon and in that thread  I remember that he was truly emphatic  posting that my MM conclusion was not  true due that things on distortion cartridge levels in reality is the other way around: LOMC has lower distortion levels.

 

Well, he is not only a LOMC cartridge designer but an expert audiophile/MUSIC lover with a long long and diverse first hand experiences listening cartridges in top TT, top tonearms and top phono stages and listening not only LOMC cartridges but almost any kind of cartridges in his and other top room/systems.

 

I never touched again that subject in that thread and years or months latter the MM thread I started again to listening LOMC cartridges where my room/system overall was up-graded/dated to way superior quality performance levels than in the past and I posted somewhere that j.carr was just rigth: LOMC design were and are superior to the other MM type cartridges been vintage or today models.

 

I'm a MUSIC lover and I'm not " married " with any kind of audio items or audio technologies I'm married just with MUSIC and what can gives me the maximum enjoyment of that ( every kind )  MUSIC, even I'm not married with any of my opinions/ideas/specific way of thinking. Yes, I try hard to stay " always " UNBIASED other than MUSIC.

 

So, till today I followed listening to almost every kind of cartridges ( including field coil design. ) with almost every kind of tonearms and TTs and in the last 2 years my room/system quality performance levels were and is improved by several " stages " that permits me better MUSIC audio items judgements and different enjoyment levels in my system and other audio systems. Yes, I still usemy test audio items full comparison proccess using almost the same LP tracks every time and as always my true sound reference is Live MUSIC not other sound system reproduction.

 

I know that the main thread subject is way complicated and complex to achieve an unanimous conclusions due that exist a lot of inherent differences/advantages/unadvantages in cartridges even coming from the same manufacturer.

 

We all know that when we talk of a cartridge we are in reality talking of its cantilever buil material, stylus shape, tonearm used/TT, compliance, phono stage and the like and my " desire " is that we could concentrate in the cartridges  as an " isolated " audio item and that  any of our opinions when be posible  stay in the premise: " everything the same ".

 

My take here is to learn from all of you and that all of us try to learn in between each to other and not who is the winner but at the " end " every one of us will be a winner.

 

So, your posts are all truly appreciated and is a thread where any one can participates even if today is not any more his analog alternative or is a newcomer or heavily experienced gentleman. Be my guest and thank's in advance.

 

Regards and ENJOY THE MUSIC NOT DISTORTIONS,

R.

Great post Raul.

As always there are many roads to Rome. No one cartridge design has been shown to be significantly better. It is all in the execution. I have heard several very convincing MC and MI cartridges. MM seems to lag a little bit behind. I auditioned the Strain Gauge. It is on the bright side do to response irregularities and it will not handle high groove velocities near as well as a MI or MC cartridge will.

I believe everyone should carefully examine new cartridges and any irregularity should be reported to the company immediately. No manufacturer can be perfect 100% of the time when it comes to these microscopic assemblies. Careful alignment is also necessary to produce the best performance. Only the owner will take the time to do this correctly. There are tools that greatly improve accuracy in cartridge alignment. I would like to suggest the WallySkater, the Wally Performance and the SmarTractor as tools that can greatly speed up this process and improve accuracy. 

Dover, I don’t think I can be wrong for asking why a “good LOMC cartridge” (whatever that is) would produce lowest groove noise. Because I’ve made no assertion. I just wanna know why. Of course I also think compliance, VTA, stylus shape, and almost everything else have more to do with groove noise than the mechanics of transduction.

Is it possible to really generalize about this?  Can we say that all mms are inferior to all mc, for example?  Or are some mm better than some mcs?  One can speak of general traits of differing technologies, but ultimately a high degree of musical fidelity can be obtained with all of them.  At some point listener preference becomes key

@dover , great to hear from you and thank you for your concern, but it was not I who made the comment re groove noise.

In the endless debate about the relevance of the live music experience as reference, as @rauliruegas has pointed out this comment from @pryso is key.  It may not be possible or practical for some, but there is no getting around it.

*** I don’t intend to say attending one or two a year is sufficient. Repetition is needed to ingrain the unique sonics or each type of instrument and vocal range. Again there is the likelihood for sonic variations from one live venue to another, one brand or design of a given instrument to another, and individual vocal characteristics. So broad and aggregated experience becomes necessary. ***

 

 

Mahler, in my opinion, no, it is not possible to generalize about the different transduction mechanisms, as regards a pecking order of what gives best SQ. All MCs are certainly not better than all MMs, to address your specific point.
