Low output MC vs. High output MC

There may be no theoretical reason that MCs could not have as high compliance as MMs, but in practice no MC comes close to the compliance of V15s or XLMs, and most are low compliance.

Cartridge: Shure V15/Pro-S
Mass: 11 gm
Compliance: 25 x 10-6 cm/Dyne


Cartridge: Ortofon SL-15
Mass: 7 gm
Compliance: 25 x 10-6 cm/Dyne
Output 0.125 mV

Cartridge: Ortofon MC 20
Mass: 7 gm
Compliance: 25 x 10-6 cm/Dyne
Output 0.07mV

I could mention at least six other Spec noted Ortofon LOMC with compliance at the same level as the Shure you mentioned.

The higher weight of the cartridge, the less effective arm weight is needed for the combination to acchieve the best resonanse frequency.
LOMC usualy weighs more than HOMC due to a bigger magnetic.

There are no compliance issues related to LOMC making it any drawback.

I think close the best compromise without knowing what arm to use would be a Compliance around 10-20 x 10-6 cm/Dyne.
Cartridge weight would in this case be best around 8-13 gram.

Combining arm, cartridge, RIAA and other TT related stuff is the art of matching with synergetic results.d
The LOMC, if money isn't really the issue, will be the best basis for this to even become an art.

is one better than the other? or is it just that High output MC carts can be used on standard phonostages in most receivers? I was thinking of trying am MC cart and I havent ever heard one. But I have read that MC cart design is basicly better than MM basic design on principle? have any of you had an MC and went back to using MM for sound reasons? I know that you cant replace a styli in an MC.




typically, LOMC's will have a more refined sound, although HOMC's are pretty damned close!

generally, unless i know for a fact that the MM is a good performer, i will go with an MC.
 
I'm guessing those compliance specs came off the cartridge database, and I think its odd that almost all cartridges have 25 x10-6cm/dyne as their compliance. I think that that's just the default value -- at work without any other reference sources to check, but those numbers aren't likely sounding to me.

Well.

It's pretty difficult to discuss anything when you define my links/references as untrustfull???

I think your own experiences, as you apparently refer to in your posts, are just as doubtful.

What can I say?

Compliance figures are not neccessarily easy to find, and not neccessarily measured the same way (and vertical and lateral figures may be different), but just looking at the Ortofon listings in the 1985 Audio Annual, the compliances for their MMs run from 45 micrometers/milliNewton (I'm guessing that's what it is) in both planes down to 15. Their MCs go from 25 to 8. Most other manufacturers MCs go are between 20 and 10. Denon didn't list compliance values, and I will admit that I was surprised by the low tracking force of the DL 1000, but the highest compliance MC I found with a quick pass through was the Goldbug Clement, which had a 36 value vertically but 13 laterally (and the 36 may have been a typo). Meanwhile, MMs with values over 30 are a dime a dozen.
Now_I don't mean to suggest that there is anything intrinsically good about high compliance -- I used to be a firm believer that the higher the better, but in the last couple of decades I have changed my mind. What is incontrovertable is that arm mass and compliance should be compatible. I also believe that low compliance cartridges that feed a lot of energy into the arm need arms with tight bearings, but I don't think this is as universally accepted.
So I feel my original point is a valid one -- that while tastes differ as to MM vs MC, HO or LO, having a good match between arm and cartridge may be more important than which type of cartridge is chosen, and that low compliance MCs are likely to need better arms than MMs to sound their best.
 
Dolph -- I'm not sure what to say -- I think those figures are wrong, partly because they don't look right to me, but partly because so many of the Ortofons in that section have exactly the same compliance figure, and almost all in that little oval, which makes it look like a default value or a provisional value. I poked around a little more, and came up with a value of 30 for a couple of the Decca FFSS cartridges, a figure so much higher than I expected that it sort of confirmed my doubts.
And having looked up some numbers, Ortofon lists the MC 20 at 17 micrometers/mN, contrasted with the OM 40 at 45.
I may be wrong, no doubt about it. Nonetheless, I'd have a very hard time agreeing that there is no difference in typical compliances for MMs and MCs. Certainly the average compliance of MMs has actually gotten somewhat less since the crazy days of the early 70s when Empire was claiming that their cartridges would track at a quarter of a gram. And meanwhile MCs have tended to go to lower tracking forces, but still they tend to track between 1 and 2 grams, with several well regarded ones more than that, whereas MMs tend to run from .75 up to 2, with most suggesting more like 1.5 or 1.8 as the upper range (this is ignoring the real cheapos).
 
Perhaps this may help, looking at the specifications for my AT31E LOMC there are two compliance figures given.

Dynamic compliance 8.5 x 10-6 cm/dyne (100Hz)

Static compliance 32 x 10-6 cm/dyne

What the difference is I have no idea.
 
Oh yeah -- I'd forgotten about dynamic and static compliances and the differences. I think that unless the compliances are dramatically different in the vertical and lateral planes, tracking forces (at least realistic ones) tend to correlate with compliances (regardless of how they are measured). So as a crude rule, lower tracking force cartridges work in lower mass arms, and higher tracking force cartridges in higher mass arms. And with normal suspensions, energy fed into the arm goes up with tracking force.
 
Live again, old thread...

Reading about design differences between high and low output MC. specifically I've been looking at Denon 103's, the Hana E, and Sumiko evo iii (both of the last two options come with high or low options).

I'm wondering how much different the homc Evo III for instance would sound from the lomc should all amplification needs be met

Nice to read and see that we had members here that knew what they where talking about, instead of how I can duck tape this table together...:rolleyes:

Think about what are your going to get, kinda hard to match a cart to an arm when you haven't decided yet. What's your preamp? do you have a stand alone stage, SUT, Head Amp?

Hahaha. That actually made me laugh aloud.

I ended up picking up a Jelco 750d on a pretty good deal. That will be run into the Phono stage of my Rogue 99 magnum

Really this thread says it all weighing the difference between low and high. In your setup, and space I don't feel you'll hear a dramatic difference nor would I for that matter. I do really like my HO Sumikos you know I have, and also love my Sumiko Talisman Virtuoso Dti and Boron that are middle output @ 1.3mv I haven't gotten a low Blackbird or EVO III yet to compare side by side. But the reality I'm very happy with what I have now and could live with any of them.

I don't bother to psychoanalyze every tinny nuance of sound, and know stepping into these MC are far better than what I had ever had with MM. It's just I know my given listening space affords only so much sound quality to happen. After chasing SQ and getting to the point I'v gotten to, it was stop chasing the system sound and build the record collection, learn that the records I buy and compare are the other half of my SQ.
 
Gawd , grab a used Empire 4000 D cartridge body and get a 4000 D/III stylus from LPGear. Amazing value for the price, even though they've massively gone to in price the past few years. That cart recently has me questioning why I bothered with LOMC's, though to be fair I haven't tried my Hana EL on my Ariston turntable .

Since getting the Ariston I've come to understand that the turntable and am choice massively impacts a cartridges performance . . . . I now understand those who have said you're better off spending on the turntable and running a less expensive cart a that will outperform a more expensive carr on a lesser table . Of course a more expensive cart on that table will sound even better although that's incredibly hard to imagine ;)

Yeah, I hear that.

Obviously the HOMC would pair better with my phono stage - and who doesn't love the simplicity of forgoing transformers. I've been buying a LOT more records lately in anticipation of being done with my turntable setup for a while, and I'm coming to the same conclusion you've mentioned. All of a sudden the prices for OMR records are seeming more reasonable.

While I realize I've been going back and forth on the cartridge topic for nearly a month now, I'm currently leaning toward the Hana EH over the EVO III simply because I have some fear surrounding nude cartridges. Any opportunity I can take to keep from damaging the cartridge seems a wise one, and the Hana is enclosed in a more classic body

That is very valid, and I live a lone and no house keeper and have been playing records a long time, well my life time.

Well depending on the match-up

I now understand those who have said you're better off spending on the turntable and running a less expensive cart a that will outperform a more expensive carr on a lesser table .
And here your contradicting with the below statement. I would say everyone should have the best cartridge, table and arm on the market. However most people with a restricted budget and say they want to upgrade from something like a SL-1200 and run of the mill MM cart, to a new set-up $1000 table that has a run of the mill MM cart. They would be far better off putting their money into a far better MC cart and stage utilizing the same table. You will get a far bigger bang in SQ for the money instead of going sideways for the dollars spent.

Of course a more expensive cart on that table will sound even better although that's incredibly hard to imagine

A better cart will sound better on a better arm and table, but this is if there is no budget, personally I really don't need to worry about it anymore. However I'v done it many times over and know if money got tight I could sell my tables and arms as long as I keep my cartridges I'll be all good on a $500 table without a huge loss of SQ.
 
To the OP I don't have a MC cart and have no experience with them but I do have a LOMM it's a Pickering XLZ with a 4500S stylus. they say it's a backwards engineered MC but electrically it is very similar it needs a SUT or a head amp ,you can also change out different stylus.I love the XLZ with some music that i'm very familiar with I'm hearing new stuff.This cart seems to improve the listening experience with more complex music like jazz, some rock and blues usually bands using more instraments especially horns.On my other TT I use a mix of Stanton/Pickering carts EEEs and stereoheadrons .Which I much prefer when listening too earlier rock, power rock and a lot of blues.More mid and bottom punch. A good example is I much prefer early beatles on TT #2with the EEE but latter beatles on the one with the XLZ there is no comparison. This is just MHO. Interested if other people listen to both types
 
I wasn't indicating that a huge amount of money need be spent. Heck, here in Australia a Technics SL1200 (between $900 & $3000) will set you back more than my Ariston RD110 SL with Fidelity Research FR24 Mk2 tonearm cost me ($800). It seems the Ariston turntable was listed rather cheaply as most want a working table , whereas this had no tonearm . Covert Australian dollars to US and it will show to be a good deal less ($608).

I'd never heard of Ariston before , and there was next to no information on the RD110 SL though what I could find on the brand suggested more digging was worthwhile . So I started threads here and on Stereonet (the view from other Aussies gives a different view point, though there's more diversity on AK) and the viewpoint of others helped me decide to buy it.

I think the thing is to be patient and have money set aside for when the bargain tables come up. . . . And as always plenty if time on Google and picking people's brains on the forums for knowledge and experience . That is often more valuable than Googling alone. Likewise you need a working table to use in the meantime . All I'm suggesting is that a great cart sounds best on a great table , that I haven't yet tried my Hana in the Ariston though suspect that when I do it will be amazing . . . Though the Empire 4000 D/I vastly outperforms the Hana EL on my JVC QL7 turntable when on my Ariston, the Hana will probably outperform it on the Ariston as well . The table plays a larger role than I'd previously come to believe.

Heck, I know you can go higher up the line than the Ariston, though I'm not likely to anytime soon. It will be a year or two before another such bargain comes about I'm sure. For now I'm going to see what I can do to improve the performance of my JVC as I'm now rather dissatisfied with it.

It's just a case of deciding where you can get the most performance gain for the least amount of money . I suspect that if I hadn't upgraded to EAR 834P copy phono stages the difference between tables would have been far less noticeable. I also should have realised that when I hit a certain level of cartridge and every new cart I tried simply seemed a step sideways from the last that perhaps something was holding them back. As such once the carts were allowed to perform to a greater part of their full potential , its one of largest leaps forward in sound quality I've heard. So yes, a cheaper cart on a better table will most certainly outperform a more expensive one on a lesser table .

I guess another point I need to clarify is that I could only ever afford this performance level with a combination of quality vintage gear and Chinese products which a copies of older Western valve phono stage and amplifier design. Often capacitor and volume pot upgrades are necessary to get the best from Chinese gear. I do everything on a budget as well in order to get the best value for money I possibly can.

I hope I've be able to clarify my previous points to your satisfaction ;)

God yes, I've lusted over the XLZ for a few years now, along with certain other carts like the Grace F8C, Empire MC5, Supex 900 etc.

Not really, IMO the biggest advantage of MCs, whether low or high output is their very low inductance, which is generally orders of magnitude lower than even low-output MMs/MIs, meaning capacitive loading becomes a non-issue. I also seem to hear a certain 'opening up' of the sound with low inductance designs, I can't say this is some conclusive or universal attribute, it's just been my experience. It's a bit hard to describe. Even the Glanz range of "moving flux" cartridges (type of MM really) exhibit this somewhat, despite being high inductance design, though in the 100mH range which is still several times less than most high output MM/MI.

Most LOMCs have a quite low effective tip mass, but so do better MMs. Many HOMCs take a penalty here, to get the higher output they often need more windings in the coils, resulting in a heavier mass the cantilever needs to wiggle around. I suppose that's the biggest drawback of HOMCs, but whether that's an issue really depends. It might not affect sound quality so much, the heavier tip mass just means ultimate tracking performance might not be as good when the going gets tough and I imagine transient response could be affected. I have to say I don't have much experience with HOMCs so can't say much about them based on my own experience.
