Moving-coil cartridges
I know that moving-coil cartridges are much loved by the hi-fi press
and by many audiophiles. I also know that there are many claims about the performance of cartridges, but there doesn't seem to be much in the way of measurements available. So, I'm wondering if there is any actual technical information available that compares moving-coil and other designs. I've done a web search and while opinions are plentiful, facts are pretty thin on the ground. It's fair enough to prefer one cartridge over another, but are any of the new moving-coil cartridges objectively more accurate than, say, a V15? Or does no-one bother actually measuring any more? Thanks, Andrew. |

Thanks, Andrew. This isn't going to satisfy you, I am sure....but in answer to your question "are any of the new moving-coil cartridges objectively more accurate than, say, a V15?" If you value transparency and "you are there" realism, the answer is yes...from many of them. And they don't have to be new....my thirty year old Accuphase AC-2 playing through a modified Marcof battery-driven headamp beats the pants off the Shure...and my old and beloved ADC XLII ... and any Grado I've heard. Back when measurements were common, the most distinquishing characteristics of the better moving coils was a much faster rise time, with a very quick cycle of overshoot and the a steady "top" to the square wave. By comparison the moving magnets and moving irons generally had much slower rise times and overly dampened transient response due to rolled off hghs (and that included the V15). So the moving coils simply sounded more lifelike and "real" (read: less "canned") when reproducing actual music. You heard this not only in the featured instruments, but also in the amount of room ambience caught that lent separation, body, and dimensionality to the reproduction. Not objective enough for you? I'd suggest a library visit into the High Fidelity and Audio magazine libraries, circa late sixties - early eighties. |

Almost all moving coil cartridges have a rising top end response deviating from flat, with a peak at tip resonance, which is why they have the square wave response you described.

From your comments, you know just enough to be misrepresentative. Have you actually measured any cartridges? I've measured quite a few of them with much better resolution than what was published in the rags of which you speak. It's not hard. This is 2009. You're at the mercy of the test record, but when the same characteristics show up with several different test records, one can draw some fairly reasonable conclusions. You can also draw reasonable conclusions about the test records themselves by comparing them with a cartridge that can be shown to be relatively flat. To rational people, it's really more important that the cartridge have flat response for frequencies that are actually physically audible. Sure, MC's usually can go out higher. But it's because of the rising top end in the audible range. That's why they usually sound different too. Turning up the treble control from flat on an amplifier generally does the same thing. Some people like this. I don't. Recordings usually have way too much high frequency information in the first place because of the unfortunate practice microscopic miking. But many audiophiles seem to like this. It also keeps the biz going by churning the market. What I say here is pretty much the same thing as Robert Greene says in your beloved Absolute Sound rag and on his mailing list. At least someone is telling some truths there. Those darned mathematicians... ;-) All this doesn't mean you can't like MC cartridges personally. Enjoy them if you wish, but please - don't pass them off as more accurate except within your own personal preferences. |

Low output MCs, are, in my opinion, much too fussy. They require lots of gain making them very susceptible to hum, and they usually require precise, custom loading to sound their best. |

What you say is true...I've had both high output and low output. But as a general rule, the low output moving coils have a lower effective tip-mass and therefore tend to sound smoother and track better. Headamps used to be a problem (an may still be) but most MC's now are designed to work into 100 ohms with some capacitor trimming capability, and people have discovered how to create much quieter gain stages (I've used the Marcoff since the earliy eighties....it was one of the first battery driven headamps and has customizeable resistance.....it is dead quiet. |

They were colored, from a frequency response point of view. A lower-midrange emphasis that some like (I among them) but others did not (as you have noted was true in your case). They had to be matched to a low mass tonearm/headshell which required some effort and $, but when done so, tracking at one gram or slightly less, they had a realistic transient response and a 3-D sense of "body" that many MC's have, and the Shures of that era totally lacked. The more common medium and high-mass arms of the day never got the ADCs to sound right. I've got open reel tape reordings of cartridge comparisons I did back in 1967...interetingly enough the cartridge that sounded a bit cold and sterile then (a Stanton 681EEE) sounds most neutral to my ears today. But the ADC's were the most realistic sounding, and the Ortofon SL-15 sounded as bright as I have previously described. |

Those thinks told you a lot...sure the overshoot told you that they were ringing at some frequency Actually, it tells you nothing of the sort. A system with both flat amplitude response and flat phase response in the pass band will have no resonances AND will have ringing. Consider the well-known Gibbs phenomenon where simply truncating the number of terms in the series will result in symmetrical ringing: the response is both the amplitude- and phase-domain is absolutely dead-nuts flat with no resonances. but if it was a single overshoot and well damped thereafter, then you knew the cartridge was properly designed and would probably sound pretty good. *Those that rang "forever" were underdamped, Wrong. Unless you are arbitrarily changing the definitions of "damped," which are quite well established without the misguided aid of the high-end realm, ANY overshoot indicates the system is under-damped. and those that had a soft leading edge were overdamped or had badly rolled off high ends This example of discussion of "rise time" and "over damped" and "under damped" and all that is illustrative of what's wrong with the high end realm and "measurements." I don't mean to pick on you specifically, Harry (though I might be accused of using you as an example), but this is a case of knowing just enough to have the buzzwords but not enough to have it mean anything. "Rise time" is but one, and on VERY narrow and limited measure that, by itself, means nothing. If you're looking at transient response, a better measure is total settling time: which not only include the rise time, but ALSO includes the time for any overshoot to approach within some accepted limits of the final value. Minimizing rise time leads to severe response anomalies in the frequency domain and being such a limited measure, has no means of defining an optimum value. Instead selecting a criteria such as the minimum time to settle to the final value gives you an optimization goal. And that's something that's quite easily defined. The result is that since the high-end cutoff of a phono cartridge SYSTEM is effectively a 2nd- order low-pass, and since such present a minimum- phase response, we CAN say the the optimum transient performance of such a system occurs when the Q of the cutoff is approximately 0.58. This is the critically damped point, the response which provides the best transient performance (minimum transition and settling time). (most moving irons due to capacitive loading). * So fix the load capacitance. Why is the incorrect load capacitance such an issue, given how easy it is to fix. The vast, vast majority of MM phono inputs compined with the vast, vast majority of cable harnsess have to LITTLE capacitance, so it's a trivially easy fix. I wasn't too surprised to find, therefore, that it had a very fast rise-time And I'll assert, with a couple thousand person- centuries of of experience, theory and practice to back it up, that the rise time is defined as much IF NOT MORE by the input signal than by the response of the cartrdige system. Explain, for example how it can be any faster than the input signal. Square wave response tests have the advantage of being quite easy to generate, quite easy to view, and especially easy to (mis)interpret. As a real measurement tool that's capable of revealing any information, square waves are extremely limited in utility and content. The complex transfer function will tell you everything a square wave does, and much, much more and without the huge interpretive ambiguity of square waves. |

Dick, for all that, I don't think we are disagreeing. A fast rise time, coupled with a single overshoot will also certainly result in an optimum or near-optimum transient response in your terms. And obviously it depends on the input signal from the test record. But it wasn't difficult to get useful square wave input off test records back in the day...and they were designed specifically for this purpose. |

There's some heavy hitters in the industry who will disagree with you about that, too. One big problem with speakers is that by the time their output hits your ear it has been heavily modified by the room. The modifications by your personal listening room is obviously not part of the manufacturer's specs for the product. Same with cartridges. IME, even more untrue. |

No matter how many times you say it, no matter how firmly you believe it, it does nothing of the sort. You assertion is that two systems with the same square wave response will sound the same, or certainly alike, and that's provably hooey. Consider the following as a practical counterexample: Take a perfectly flat, linear- phase system. It will have, for its bandwidth, "perfect" square wave response. Listen to it, it will sound fine. Now, take the input, delay it 10 mS, and sum it with the output of the system. Put a 1 kHz square wave in to the system: it will have an identical square wave response. Now, listen to it, it will sound absolutely dreadful. You keep going back to the ringing canard as if it had any signifance in and of itself. A PERFECT band-limited system MUST have a substantial amount of ringing, Gibbs says so. You say different, in contradiction to well-known facts. |

I've already explained to you how square wave response confuses frequency response (which matters) with phase response which in general does not. Please provide equations that unambiguously convert square wave response into traditional or non-traditional measures of nonlinear distortion. Of course, no such thing exists nor can it exist because of all of the confusion factors. |

In this regard, cartridges are much like speakers. While measurements can tell one a lot about speakers, ultimately, you have to listen. Same with cartridges. I don't see how this can possibly work. All that listening will tell you is what you prefer, but I was asking about fidelity, which isn't the same thing. Unless you happen to have the master tape that was used to do the cutting, there's no way to judge fidelity by this method. Later you say: Accuracy is not really important in a phono cartridge. The only thing that is important is how the cartridge sounds with the records you listen to on your system. OK, you don't believe it's important. But surely you can't be denying even the possibility that one cartridge might be more accurate than another. There are more important considerations than frequency response, which as I said earlier, is largely irrelevant these days. Those measurements I have seen of cartridges suggest that there can be quite wide differences in frequency response, certainly wide enough to be audible. And surely frequency response differences are going to have a pretty big effect on the way they sound. Jim Lesurf's rather wonderful web page [1] shows that a v15, properly loaded, has a pretty flat frequency response, and it tracks well, as low distortion, and so on. So, whatever is wrong with the v15, it isn't frequency response. Things like tracking ability, transient response, suppression of surface noise (largely a product of stylus shape), channel separation, and low distortion are more important than a flat, as opposed to a rising, top end. OK. So, to return to my original question, is there any reason to believe that moving-coil cartridges might have an advantage in any of these areas? I am beginning to wonder if the moving-coil cartridge is better than moving-iron in the same way that, say, single-ended triode amplifiers are better than modern solid-state designs. In reality, not any better at all from a fidelity point of view, but some people prefer the sound. This question surely is important because there are a lot of valuable sound recordings on vinyl that are being transferred to digital media. I have heard unsourced rumours that organizations like Sony and the Library of Congress snatched up the last few V15s for this purpose. Assuming this is true, might they have been mistaken? Should they be using a real "Stereophile Class A" design such as the Air Tight PC-1 or Transfiguration Orpheus? Andrew. [1] http://www.audiomisc.co.uk/HFN/LP4/NewLampsForOld.html |

Most high end audiophiles lack what it takes to properly load most MM cartridges so that they have optimum response. So, they evaluate cartrdiges based on unecessarily non-flat response. Most high end audiophiles do not have references to compare to that have truely flat response. So, they wouldn't know flat response if it came up and bit them. ;-) |

The #1 problem in cartridge design is minimizing moving mass while providing appropriate durability and rigidity. So, I'm wondering if there is any actual technical information available that compares moving-coil and other designs. The challenge has always been to make a couple of coils of wire less massy than an iron reluctor or a small magnet. I've done a web search and while opinions are plentiful, facts are pretty thin on the ground. It's fair enough to prefer one cartridge over another, but are any of the new moving-coil cartridges objectively more accurate than, say, a V15? Not that I'm aware of. Or does no-one bother actually measuring any more? It's very easy to do with a computer and a good test record. I would have done it long ago for some MC cartridges but I don't have access to any. |

The challenge has always been to make a couple of coils of wire less massy than an iron reluctor or a small magnet. Difficult to do. Usually efforts in this direction led to coils with just a few turns on them resulting in extremely low output voltages making said cartridges very susceptible to hum, and requiring either a step-up transformer or a pre-preamp. Low-output MCs also require custom loading with regard to input impedance requiring that the user try a combination of capacitors and resistors to get it right. Most never do. I learned a long time ago that high-output MCs designed for standard 47K-Ohm phono inputs offered the best compromise. The slight increase in mass was more than offset by the ease of amplification and lack of fussy (and usually totally empirical) resistor and capacitive loading techniques. I've done a web search and while opinions are plentiful, facts are pretty thin on the ground. It's fair enough to prefer one cartridge over another, but are any of the new moving-coil cartridges objectively more accurate than, say, a V15? Not that I'm aware of.

The effects were noticeable only with selected good records, during certain passages and with experienced listeners, but even then, the differences were not particularly different statistically. During the second part of the test, the Shure was equalized using a Technics 9010 parametric sequalizer so that the response was within 0.2 dB of the Ortofon. Again, the results were close, with the interesting result that the moving magnet gained a slight edge over the moving moving coils, not so much by increasing its score on the evaluation sheet, but by causing the marks given to the moving coil to drop slightly. It is very tempting to generalize from a test of this nature. One listener was able to pick out the moving coil cartridge consistently and expressed a clear preference for it. The closeness of the results surprised several listeners, particularly the moving coil aficionados who were embarassed to find that they had given their votes to the moving magnet." Klaus |

As a concept, you're probably right. You can make a good or a bad magnetic cartridge using any of the three generating principles (moving coil, moving magnet, or moving iron - sometimes called variable reluctance). Agreed. And in the day of, I experienced all of the above personally. Cartridge design is probably, at least as much as speaker design, dependent upon improvements in materials and manufacturing technology to move forward. Regrettably untrue due to the fact that even 30 years ago, the limiting factor was that nasty slug of vinyl that this whole discussion centers on. The reason why we moved on to digital was that it was no secret then, and since the laws of physics have not changed in any relevant way since then, it is no secret now; that as long as you use a relatively slow-moving piece of vinyl with mechanically transcribed analog grooves, ca. late 60s early 70s performance is all you are ever going to beat out of the vinyl dead horse. There were several attempts do take vinyl to the next step that failed miserably. One was the DMM process which removed a mechanical step from the tooling process of pressing the same limp old LPs. Then there RCA's lame attempt to keep the mechanical disc format but change the mode of data coding from direct analog to FM and possibly even digital, with a contact-based capacitive pickup. This actually came close to seeing the light of day as a format for distributing video. Optical-based storage blew it all out of water before it ever went mainstream. The Laser Disc in both FM and digital audio formats was generally accepted technology for years before the CD was introduced. There is no doubt that even a relatively inexpensive cartridge these days from Audio Technica, Grado, or Sumiko, to name a few, is equal to or superior to the best cartridges available 20-30 years ago, I own one of those Grados and it has a chance of approaching the M97XE. yet they use the same generating principles as they did then. More significantly they have the same old analog noose around their neck. What has changed are the materials used in the stylus suspensions, the stylus shank itself, and even the magnets used. Not so much. Concurrent with that are manufacturing processes for shaping and polishing the stylus as well as how the stylus is mounted to the cantilever and even assembly techniques. That's probably more automated than it was in the day. The inflation adjusted price of a Grado Black is still far more than a late-60s V15. |

Klaus Back in that day, a Dynavector Diamond or Ruby, an Accuphase AC-2, or an original Koetsu would qualify....it is not so much price...the Ortofon MC30 (at $850) was their top of the line, and it was one of the worst sounding top-of-the-line MC's to ever be put on the market. The Diamond cost in the same range as the Ortofon ($670) and the Dynavector Ruby was cheaper still ($310), about the same as the Denon. The Accuphase in this same price range ($475) was so good that it has served as my standard ever since, and has stood off many other (more expensive) contenders. The simple fact is that what was considered high-end was determined by the listening acclaim that certain cartridges garned among audiophiles, and what was low-end the same. For most people in those days, the Shure and MC-30 ranked lower-middle and the Denon just a notch above. To repeat, it had little or nothing to do with cost. |

How do you define a high-end cartridge? Subjective criteria or impressions cannot be used because different individuals have different tastes and because of the fact that in-ear frequency responses between individuals may show substantial differences: So how do you OBJECTIVELY define high-end? In 1982 the Shure V15 IV retailed at $200, the Ortofon MC30 at $850, the Denon 103D at $295 (prices from Audio annual component directory). Was the $850 Ortofon high-end or had it to be a $1000 Denon DL-1000, or a $1300 van den Hul. When is a cartridge high-end, when is it “only hifi” ? In the late 1970s the Grado FTE+1 cartridge costing a mere $15.00 was highly regarded in the high end community. Although it picked up some hum as it approached a turntable's motor and exhibited the so-called "Grado Dance" in a LP's lead-in grooves, accolades came from every corner. Turning to CD players, according to some reviewers at Stereophile magazine the mass-produced Radio Shack Portable Optimus 3400 for $180 was ranked in the high-end crowd. I owned a FTE+1, but for CDs I still have and use the famous mid 80s Magnavox CDB-650 which is completely functional (amongst more recent ones). As of today it feeds a vintage tube ARC pre-amp. |

Which ARC preamp do you have? I still use an SP-11 and to this day have never heard anything better! |
