Introducing the Phono Cartridge Measurement Library

I measured a second Stanton a month ago at 270pF:


I highly recommend to use the index to see if there are multiple measurements for any particular cartridge. It is best to compare them.

For that first measurement I posted last year, I got "better" results with a higher loading. As mentioned, and as to be expected, the difference was small. The measurements were made for an older version of the script that used only one channel, which is why azimuth adjustment was a bit off. However, as I mentioned in the post, by the time I opened up the library I had already sold the cartridge and so I posted what I had. Use the newest results.

Maybe I'll measure the new one at ~300pF again when I have the time.
Yes you are right I'm happy with subjective results after using recommendations from manufacturer of 275pF I ended up at 300pF great balance hear.

I never linked to 
But here you go.
The file I want you to have is to large for this site.

Notes:

  • Crosstalk/azimuth set using Ortofon test record (sweep, below)
  • Suggested load 140-250 pF and 39-47 kOhm
  • Cartridge body resonance at ≈400-500 Hz

Well yes the Super OM30/40 are one of the current cartridges with linear fr but likes a bit lower R, like 42 kOhm. Distortion isn’t super low though. Maybe due to short cantilevers? Yours must be an old one coming with a chart. FG or van den Hul stylus?

I found the graph on the Internet, I do not currently have this cartridge
The date, 1985, suggests that the graph concerns the OM40 which used Nude VdH. From what I remember, this stylus was mounted to the OM cartridge (not Super OM) at that time. Super OM and OM have different electrical parameters (resistance, inductance) and a different mechanical design, different housing, different pin design, improving the response in the high tones
I am considering buying a set, SME III tonearm, SME 30H tonearm tube + OM40 stylus. If I decide to make a purchase and mount the set to the Technics 1200GR2 turntable, I will definitely measure it.

Early OM40s had 35-40 cu compliance. So needs light arms.

Please do it. The SME III is a masterpiece of an arm for higher compliance cartridges. It always has been downgraded and overlooked because it is not "sexy", but from a technical point of view is the best arm ever for "soft" suspension cartridges like many, should I say a lot more than ever, now on the market.
 
Shure V15VxMR

Shure V15VxMR old | 1.45 g | 47_63 kΩ | 140 pF | CA-TRS1007.png

  • Old (first) beryllium/MR stylus but distortion looks ok at 5 kHz (≈-30 dB)
  • Drop after 1 kHz as expected from other measurements ("warmer sound")
  • Suggested loading around 250-300 pF and 50-60 kOhm (current one not optimal)
  • Current loading ≈140 pF, 47 + 63 kOhm left/right
  • Shows why JICO SAS/B works fine with this model but not with the original V15V-MR:

Too few picofarads, too many kilohms, very bad azimuth. Everything is wrong ;)

It will nevertheless never be a V15V-MR. The "x" variant has poorer internals. Azimuth is only wrong on the CA-TRS1007... ;)

Very nice frequency response curve upgrade with the Jico.
Won't be able to hear most of the treble boost and could adjust the turntable setup if unpleasant.
Manufacture 25db at 1k is pretty poor for what this was marketed at.
Could be the internals as you say.
Going to have a look at the V15 VMR specs.
Manufacturer rec. cap. Loading 250pF
140 pF is very low, where will that work?
Did you test Jico option, or should I read the information given?
My azimuth from manufacturer is perfect.
Internals? It's still the best cartridge in SQ I've ever owned.

With the vast majority of MM carts and most definitely Shures -pay attention to whatever the OEM recommended for phono input capacitance. This is a fine cartridge and if you've actually found one with a intact and useable VN-5MR stylus -one of the best ever made. Enjoy.

1989 Article

Shure gets a bum rap from everyone. Audiophiles are down on them because they're so cheap—the V15 Type V-MR selling at a typical street price of $129. Not that most of these 'philes have actually heard the V. And if they have, it's probably in a grotty arm on a budget table in a Cheapskate system. Put the V in a Rega RB300, or better yet in an SME 309, and you may be amazed at what it can do. Cheap arms can make the Shures sound hashy, harsh in the treble. It's not the cartridge; it's the arm.

High-end dealers are down on them because they would be lucky to make $10 margin selling a V15 Type V-MR; you can buy it almost as cheaply as they can! That makes it a terrific recommendation in my book. If they carry the V at all, which is doubtful, they are not eager to demo it against, say a $1200 moving-coil, on which they might make up to $600 margin.

Here's another reason to go for a Shure: record wear. There isn't any with a properly maintained Shure. I've been using mostly Shures since 1958 and I have, in all that time, never worn out a record. True, I have so many records that I'm not likely to wear out an LP with any cartridge, but my library wasn't always so large.

Last summer, I visited our esteemed editor John Atkinson in Santa Fe. He played some records on his Linn. They were all worn—every one. Not from neglect, but from cartridge gouging: low-compliance moving-coils that just scraped their way through the vinyl. Now tell me: what's worse? Losing a little detail by using a Shure, but saving your records? Or extracting a little more detail with a low-compliance moving-coil but rendering your records so worn that you soon won't want to listen to them with any cartridge? With most of your LPs now irreplaceable, give this one some thought. I have, and I'm sticking with Shure.

In the September '89 issue a reader wrote and asked if I really meant it that a typical moving-coil, in a typical audiophile's system, might last six months or so. I did mean it. That's how long most of my tweak friends seem to keep a particular moving-coil before replacing it with another. Some 'philes spend $2000 a year, year in and year out, on moving-coils. This is insane.

Buy a Shure V15 Type V-MR and you can rejuvenate it instantly with a $79 replacement stylus (typical street selling price, again). Incidentally, the replacement stylus for the Type V-MR will fit in the Ultra 500 cartridge body and work perfectly, so far as I can tell. What's more, because a Shure tracks so lightly and so well, the stylus is usually good for at least 1000 hours vsmaybe half that time for a low-compliance, poor-tracking moving-coil. At $79 for a replacement stylus, that's 8 cents an hour to run your cartridge. If you buy a $1200 moving-coil and use it for, let's say, 500 hours, that's $2.40 an hour. It costs you 30 times as much!—Sam Tellig

On another thread avout me not loving my AT740ML, most people said that cartridge sound is mostly about the frequency response until you get to mistracked inner grooves. I wondered if the answer was IM distortion that this thread isn’t investigating. I was sort of brushed off. A few days ago I was reading a cartridge review where they measured IM distortion as part of the test. It was at clearly audible levels in a subjectively praised cartridge. I can’t find it now but here is a thread where someone does a bit of testing just for fun. The caveat is that the test record is old and was cut at a different angle than more modern records. It shows shocking levels of IM in a vertically modulated groove and even in the horizontally modulated groove IM distortion was much higher than harmonic distortion. (Test tones are 200hz and 4khz)

 
It was at clearly audible levels
What level is that? How was audibility determined?

EDIT and yes, having performed my own IMD tests with those same test records, his results are highly suspect.

I never had any cartridge mistrack inner grooves, Nor do I hear problems with inner groove distortion . Maybe my hearing is worn out, I remember the inner tracks on. Procol Harum Grand Hotel used to sound bad in the last track in 1974.

Audio Technica OC9ML/ii , 33PTGii , Jico SAS B, Technics National 270CII + 6449 Tonar hyper elliptical, AT95E, AT3600L,

I use the inner track on Eric Clapton Unplugged to listen for problems, kind of easy track to do , but is is anyway a common track

Do the Tacet fricatives test?
 
fricative?, I got the Tacet record yes, I rarely use it as it is kind of poorly made and not really useful, the design annoys me

I do notic that the microline stylus are better than simple elliptical when reproducing sibiliants tszz shhj etc
