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.

I used to use the Multicap RTX caps for critical applications. (Those are the polystyrenes.) But in my listening opinion, the teflon capacitors that came along later are far better (REL or other). In fact, now I cannot bear the RTXs, and I have a bunch of them in many different values. I also found some 2uF/200V polystyrenes (so not applicable for RIAA or hi-pass filtering unless your filter is set at a high-ish frequency), made by PAS (Pacific Audio Supply), that are unsurpassed for output coupling capacitors. I originally bought 36 of them to use as a high pass filter in my Sound Lab speakers, and when I totally removed the high pass filter in the speakers, I ended up with a box full of the PAS which I then tried experimentally in output coupling and now love. Sadly, PAS is now defunct. I have several PAS polystyrene also in 0.22uF/600V; Ralph used to use them as internal coupling caps in his OTLs. They’re superb but fairly large and don’t fit everywhere. For low value capacitance below 0.1uF, I have found the Russian silver mica capacitors the most absolutely transparent. I use them in RIAA. They were or are cheap on eBay. I guess my point is that no one company or no one type of capacitor is "best" for all applications.  You have to experiment and listen.

Dear @terry9 : Please: can you share with me the link of your air dielectric source and models? here:

Appreciated, thank's in advance,

Surplus Sales of Nebraska. Many values, all small. At least, that was years ago.

@lewm  Interesting experience of yours. I ended up using my teflon film and foil for component level power supply filters. Don't suppose you'll like to sell some of the RTX?

@mijostyn I should have mentioned a possible x - intercept. What you wrote is true if everything is linear and the x - intercept is 0. That is, there is a noise floor.
