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 have a box of Russian Cap's for a Speaker Xover design that was put in place for me.

@lewm  : " I have used.01uF and .022uF values mostly, in an RIAA circuit,  "

Was a RIAA circuit designed by you?. In a RIAA circuit using caps adding capacitance ( somewhere ) changes the RIAA deviation curve but if was you who designed it then you made a new calibration and if not that was a very bad " move " even if you like the result.

I don’t design RIAA circuitry. That’s over my head. I substituted.022 uF caps into an RIAA that already required .022uF.

Dear @lewm  :Through my audio years I modfied the elctronics I owned but  never touched any RIAA circuit mainly for what terry9 pointed out about in this thread.

Of course that all depends of the manufacturers quality designs and the owner targets.

First issue with the RIAA it's that is not linear but a developed curve whre any frequency change affects around two frequency octaves and this fact means that will introduce a coloration/distortion added that many times and depending of the quality system resolution we can or not aware of it.

It's not only about colorations but RIAA overall deviation.

In our designed units we can't even change a 0.022 uf and not only for all those but we were and are so demanding that going from measured 0.022uf to 0.023uf has a consequence, nothing comes by free depending on that design and your targets and we have to think that that cap is not only the cap but its very close relation ship wwith the other passive parts.

Well, that's me and nothing more than an opinion.

Russian silver mica capacitors on eBay and give them a try....

These are absolutely as transparent and neutral as a TI TX2575 resistor. 

This is not possible. Capacitors have phase shifts, resistors don't.
