Top 3 high compliant mm/mi cartridges

Dear Fleib: +++++ " A cart with a cu around 50 (Sonus) might sound sluggish in a med weight arm. Some with a cu around 20, sound sluggish in a heavier arm. " +++++

My Sonus Dimension 5 sounds nothing less than spectacular on the Grace G.945 that's a medium EM tonearm and the Gold Blue sounds prety good on my AT 1503 that is more on the high EM side.

As I posted if we can is good try to put the resonance frequency around 8hz-10hz but if not the best way to go is: listen and decide.
Through the years and through a lot of test procedures with a lot of different MM/MI cartridges I found out that that tonearm/cartridge resonance frequency is important but not to important for we " stop " what we doing till we have the right EM tonearm. I found out that we can achieve more differences on quality performance through headshell changes ( different build material and headshell shape. ) than trying to match that resonance frequency.

I own the Ortofon MC2000 ( LOMC. ) that's a heavy weight cartridge with a high compliance ( for a LOMC cartridge. ) well this cartridge received a rave review through Audio magazine ( december 1984. ), the cartridge was tested in a whole Technics combo ( TT and tonearm. ) where the resoance frequency ( measured twice because the reviewer can't belive it can works. ) was: 5.1hz.

One of the LPs that the reviewe used was the Telarc 1812 recording and you know what: he loved, the cartridge performs with out any trouble on the bass with those " terrible " recorded canon shots.
The reviewer was nothing less than B.V. Pisha it self.

It was the best cartridge/tonearm match?, from the resonance frequency issue point of view certainly was not but performed as a " best match ". I already had a lot of this same experience with several cartridge/tonearm combinations.

Analog is a set of " imperfections " where the usual theories many times does not conforms as we could wait.

The performance and relationsship between a cartridge ( any ) and a tonearm ( any ) is " complex " because involve several and different factors that have influence on that performance level combination.
IMHO and as I posted that resonant frequency cartridge/tonearm subject can't give us a precise predictable quality performance level behavior.

Till today I never readed or found out any kind of " model " that predict(ed) in precise way what I will be listen in any cartridge/tonearm combination. Tha's why Dlaloum's ( in the other thread. ) " intent " is not only a enormeous one but with no " predictable " precise cartridge performance: at least not what we have to wait when listen it.

I respect your opinion that I assume comes from first hand experiences.
My first hand experiences as some other persons first hand experiences are what I posted here.

I'm not saying that the resonant frequency subject is not important because it is, things are that IMHO that sole parameter is not enough for we can decide which tonearm we could use it and till I have that " model " that can predict the cartridge true quality performance my advise is: please listen with what you have and decide according.

Regards and enjoy the music,
Raul.

Hello Raul,
I agree with you that too much is made about cu and mass. It is often hard to predict the outcome of a highish cu cart in a heavier arm. I never owned a Sonus cart and therefore never tried one on my Sonus arm. That might be interesting, especially with your results on a much heavier arm. On the other hand, my M20FL Super seems to sound sluggish on my med/heavy arms. Maybe it's the combination, but it seems to sound much better on an 11g Alphason 100S or a 8g Unitrac.

Light weight/low mass arms usually don't sound good with heavy, low cu carts. At least that has been my experience. Resonance goes toward the audible band and the structure of the light arm can't handle the mass or energy.

I didn't mean to imply that strict rules had to be observed, matching cu to mass. With a good tracking cart of 20cu, a wide range of arms can be used successfully. I found this to be true with my Stanton 980. Results were somewhat different with the M20FL. It seemed sound thicker, although I didn't even try the 980 in my heaviest arm.

Dear Lew, I would love to read about your impression reg.
AKG 8 ES and other MM carts 'waiting' for your time.
But now your project with SP 10 mk3 is at last finished
we may hope to read less 'technical-theoretical' speculations and more musical 'reports'. I know that you are also a musician and I have the inclination to trust
more a musician then a technician.
Regarding AKG carts . According to AKG the problem was the
suspension ( 'rubber ring'), say, hardening as function of
time. To avoid probable liability AKG destroyd all their
stocks of carts and styli. I have never heard about 'coil
problem'. So even those who own the 'NOS' stylus have no
quarantee that their example will be ok (sorry).
So it seems that those who lack the stylus should follow
T_bone's suggestion (04-23-11) while we all may hope that
some or all retip services are also able to repair the suspension. If some of us is confronted with the coil problem the solution is obvious: bay an other corpus.
I posted three of them + a broken stylus (pace T_bone) to
HIFI79STUDIO and ordered the cheapest retip: aluminium cantilever with a elliptical stylus (100 Euro). If the 'pudding' is 'tasteful' I may try boron cantilever with some more 'exotic' stylus.

Dear Nandric, My memory for the cause may be faulty, but it is demonstrably true that many of the AKG cartridges that come up for sale on eBay are described as "one channel is dead" or "dead but stylus is good". A faulty stylus assembly should not cause one channel only to go completely dead, as far as I know. So there has to be some other explanation for the plethora of defective AKG cartridges. Ne c'est pas? I thought I had read that there was an issue with internal wiring, but I certainly could be wrong.

Dear Raul, Since you mentioned the MC2000, let me also say how much I am enjoying your Ortofon MC7500, in a 10.5-inch Reed tonearm on my SP10 Mk3 (finally). And now, back to MM/MI cartridge discussions.

Dear Lew, I need first to complete the statement I made.
I see often my omissions after I posted my contribution . My sentence should be: ' I have the inclination to trust more a musician then a technician ( +) in musical matters'.
The AKG carts are rather cheap on the German ebay so the
possible 'coil problem' is much more easy to solve then the
stylus problem. I already bought 3 AKG 8ES 'super nova' for
less then 50 Euro. Anyway I hope that one of the 3 will
have 'fantasic coils'.
