Introducing the Phono Cartridge Measurement Library

[morillon]

the orto is announced at 5 ohms...
+16 is a big mistake for antiskating... much too much... (big mistake in the last hifinews lp and old at +15db)... not for antiskating..but tortures tests !
for the rest I don't say anything and invite you to check all that... including the validity of your riaa support and good luck.....

 

[Palmer]

Going out on a limb here, I guess the question is what do you want to achieve in your endeavors?

I haven't had a Ortofon Kontrapunkt of any variety come through, but if memory serves me well, these do come with a response plot from the manufacturer.
I would venture those plots to be highly accurate.

I have been contemplating to replicate a cutter head, in reverse if you will, to be able to do testing without a table, arm, record to interfere, and minimal handling of a cartridge.
If I get around to it.

 

[morillon]

your approach to antiskating is exactly a huge load of crap... ;-)
and it has made retippers happy for decades.. ;-)
and you will never have "optimal" results on a daily basis.

 

[Quando]

I would very much like to change the anti-skating value. What value do you suggest for the Ortofon Kontrapunkt 2.5 grams of pressure?

The tonearm set in the turntable with zero pressure and zero anti-skating stands still, does not run to the center, does not run to the rest.

Please stop posting here. You have done nothing but create confusion since you started. You have refused to take advice or engage with others in earnest. You have demonstrated a lack of understanding of the issues you are concerned about, have refused to read the introduction and guides, and your overall attitude and approach has been rushed and extremely sloppy.

If you want to see if anyone you haven't pissed off will help you sort out your issues continue this on the script or measurements threads. If you refuse to do so I will ask the administrators to give you a timeout from this thread.

To anyone new here: if the measurements are not in the index then they are not reliable. Certainly most have issues (the measurements may be limited but they do not lie), but we have to have standards here.

Shure V15V-MR

I finally got hold of the original NOS VN5MR stylus!!!

Below are my tests with various loading and capacitance:

With original stylus this cartridge is just awesome!
I think I prefer the 65k - 95p loading best.

Notes:

• Stylus is NOS max 10hrs of use
• Turntable: Technics SL-1210GR with KAB Fluid Damper
• Headshell: Audionix CS-6
• VTF: 1.50gr with brush
• Phono stage: HusaRIAA v2 (http://tinyurl.com/45ke55cx)
  • Capacitance: ~95pF-142pF (total capacitance)
  • Loading: 48kΩ-65kΩ
• A/D: ASUS PRIME B660M-A Line In and Audacity
• Test record: Clearaudio CA-TRS-1007 side A

Awesome. Welcome to the club! A great thing about this cartridge is that it helps confirm whether your test record is reliable (and phono stage RIAA too) and lets you see any issues that you can compensate for--at least in your head. Interesting loading options too.

Now measurements look correct. Just add

AT95E

In the first row of your post.

Fixed
I restarted the sound card settings and now it works properly.

Having looked over virtually every cartidge in the library, I’ve come to believe that the Shure V15V-MR is pretty much the pinnacle of cartridge technology, both past and present. I’m running an Ortofon 2M Black, which I was able to get pretty good results from but have an itch to add a second TT and play with another cartridge(s). Is my impression on the Shure correct? At the same time, I’m wondering if my Ortofon, which I've posted here, is good enough that searching for a Shure may not be worth the trouble. Am I missing something here?

In addition, seems there is very little MC content in the library? Is one worth pursuing? I have an empty input for an MC on my Apt, and have always wanted to try one, but I don't want to throw away money/time.

I'm pushing sound through a pair of KEF Reference 1 Meta's, so if I've got a system that should be able to benefit from an improved source.

Look forward to comments/concerns/debate...

The ones produced today for linear response; Nagaoka MP-500, Ortofon super OM30, or a JICO SAS/B for Shure V15-VIII, -VIV or Vx. JICOs seem to vary a bit in the top octave. Would love to see Sumiko Pearl with SAS MM1 stylus measured.

As you probably know already, stylus replacement down the road is the drawback with moving coil. I have had Soundsmith retip carts for me, and I find the cost rather reasonable and the work outstanding.

Peter Lederman has excellent videos out there about the challenges in cartridge designs and he knows what he is taking about. No affiliation other than being a customer.

Best non-moving coil I had was the Garrot Brothers P77i , but I haven't looked what the stylus availability is these days. Can be had just shy of 700.- and I'd buy it again.

Garrott Brothers P77i Moving Magnet Cartridge - Len Wallis Audio

In order to understand how the Garrott P-77 gives such unique sound quality you need to know something of its special design features. Until now, it has been generally considered impossible to harmoniously combine the best features of the 3 major types of stereo cartridge design - that is...

@JP still have the Ortofon Super OM30 around? Any measurements of that one?

 

[JP]

I do. Winter is coming again. Too fast - still need to winterize the boat and get the docks in, amongst other lower priority items. Think I may catch up on some audio stuff late November.

 

[JP]

I also have the auto cut and trim for the script working - just need to integrate it.

 

[Thomas_A]

Ok, sounds fine and I understand, time is always a limit. I never got to NY and Boston this year. Hoping for next summer.

I don't think Shure with Jico Sas is linear, but maybe I'm wrong.
Without a lot of control over the capacitance and resistance in the preamplifier, it will be difficult to set a linear frequency response of the MM cartridge.
Today I compared the AT95E and Ortofon Kontrapunkt. If you look closely, there is no very big difference in the unevenness of the frequency response.
However, it is impossible to compare how it plays at all. At all.

In some time, I will check the Shure Ultra 500 / Ultra 400 / 140HE/ 120HE and many others. I am curious about these measurements myself.
A terrible thief of time
