Yes, and magnets.

I admit I don’t fully understand the components of the suspension versus the stylus.

The body of the MM cartridge lasts indefinitely, right? When you replace the stylus, you’re replacing the stylus, cantilever, and suspension in a single product, right?
Yes - the stylus includes the magnets, the mounting mechanism, the suspension, the cantilever and the needle.

The suspension is basically a rubber "doughnut" around the end of the cantilever - as well as "suspending" the cantilever, it also provides a level of damping - the firmness of the suspension then defines the optimal tracking force (VTF) and the optimal arm mass matching for to the compliance (give/firmness) of the suspension.

A good "retipper" - can replace the suspension alone, on a NOS needle - however, keep in mind that once that is done, the optimal VTF/Compliance parameters will be defined by the new suspension rubber and not the original specifications.

For those who have setups that are best suited to lower compliance / higher VTF, replacing the suspension has the potential additional side benefit of increasing VTF and optimal arm mass (by choosing a lower compliance suspension rubber).

To bad I broke off my Shure V15 V HE beryllium then, but I just bought this to cheer me up

What's the condition of the cartridges? The distortion above 5kHz is interesting.
It is almost unused. It is also different with the Ortofon test record.

DENON DL-60 ORIGINAL?? ON DENON DP-51F

1694010475255.png

1694010498440.png



Sounds OK
  • Cartridge: DENON DL-60 at 1.8g. Azimuth not optimized
  • Stylus condition: unknown came with turntable bough form a widow. DL-60 cam with tie TT originally.
  • Test record: Clearaudio TRS-1007 side A track 1&2 L/R stereo
  • Turntable and arm: Denon dDP-51F Measured peak wow <0.06%. Dynemic Servo tracer arm coundteracts resonance
  • Phono stage and loading settings: Cambridge CP2
    • Capacitance and impedance:47kohm 310pF with cables
  • Cable capacitance
    • 80.pF accrong to Stereo review May 1982. +220pF RIAA.
  • ADC: Tascam 144mkII
  • Recording: no adjustment on balance, no Azimuth adjustment on cartridge, 96k

At the moment, is the flattest cartridge the Shure V15 Type V? The Ortofon OM40 and DL-60 both look impressive as well.

So first of all, these measurements are excellent, but beyond my capability to do myself. I'm personally not all that enthusiastic about searching for a used or NOS cartridge and sourcing a new stylus for it. I'd rather buy something off the shelf. So, I'm curious about the "modern" cartridges that are available through conventional audio dealers. I've seen comments about how the best ever made was right at the end of the vinyl era, but have we really proven with measurements that the currently manufactured cartridges are worse, better, or the same? I've looked at the third-party measurements are available, but the number of tests is not particularly large. Is there any appetite out there for measuring "modern" cartridges.

There are a lot of new AT that are good. Also Ortofon super OM30 is a good choice.

The installation of the software is somewhat specialized and challenging if you have limited computer knowledge but the magic is that this is that if you know how to
A) make a recording
B) trim a recording

You can do this with your own gear!

Seems quite worn. Distortion is high. I'd not use it. If you do try cleaning the cantilever with 99% alcohol and a little distilled water. It looks grungy and it might be a bit weighed down. Here is a near new one. Old measurement. I'll re-do it in the future.

More will come as the thread gets more views and interest. You can help by pointing to it in other forums. No need to be preachy about it. I think people will come around. They just need to know that it is possible to measure cartridges.

I just ordered a Sumiko Pearl simply for the measurement. Might make a good cheap option. Crosstalk is spec'ed at -30dB and that hints at quality. Who loves you guys?

If I came across as preachy I very much apologize. Not my intention at all, and maybe i didn’t spend enough time composing my comments. I am very curious about how/if modern manufacturing and materials might yield improvements to performance.

I didn't mean that you were being preachy. I just meant that bringing up measurements on vinyl forums is like dropping a grenade by your side. Best to be casual about it.

Of course, but someone has to buy those modern cartridges and then set them up and then test…. In contrast, getting end users to learn how to run their own tests is easier :)

HifiNews has the best (only?) industry tests of modern cartridges.

Mention my name - smoothing things right over. :eek:

When back from a bit of travel I plan to order a Grado Gold 3 for testing. Xtalk 35dB!
