Stylus/cantilever stiff and noisy--WARNING!


If you can hear the music from the needle (at the needle/cart) when volume is minimized, cue the tonearm up as soon as possible.

The suspension elastomer on the stylus has stiffened up and will not only sound poorer but can damage the grooves because of lack of compliance.

I've had this happen a few times and it seems to happen very quickly. Literally, a week or two after last playback.

This usually happens with older styli or new-old-stock styli or carts.

I was able to get a an ADC (1977) stylus working after a wd40 treatment (this is common "cure" for the issue). But the problem came back very quickly.

A "feel" test (fingers on stylus) might  also help get the "feeling" for good compliance vs. bad.

I had this happen again on some new-old-stock Shure replacement styli.

I'm not certain if there is some sort of test or "rule of thumb" that us vinylphiles can use to:

(a) ascertain it is indeed elastomer/suspension related

(b) gauge the ORIGINAL mechanical compliance of the stylus.

Maybe comments related to following might be useful :

Shure , Stanton or Pickering stylus are stiffer than other manufs.

DJ cantilevers are stiff.

Mass of tonearm vs stylus compliance.

I have a Rega Ania Pro cartridge  on a Rega Planar 6 that is a year old. The rhomboid suspension pivot on the cantilever is s as supple as ever. Yet, I can hear the cartridge from several feet away when the amp is turned off. I'm running 1.9 gram tracking force so nothing unusual.

 

I don't think hearing the needle tracking in the groove at some level is cause for concern. Just ordered a Hana Umami Blue so will see if that new cartridge can also be heard.

"Stylus", not "stylist".  You can get your hair done by a stylist.

I would never ever recommend putting any sort of rubber or other restoration product on a cantilever or any other part of a cartridge suspension.  First of all, the parts are so tiny that you, an amateur like me, have no hope of not splashing the material onto other parts of the cartridge that would suffer from it. And I repeat what I wrote above, a cartridge is inherently microphonic, and hearing faint music from the cartridge is completely normal.  True, in some cases it is more audible than in other cases.  That may indeed have to do with cartridge compliance, but I think it also has to do with the other components in the chain and the recording itself.

Whether it’s the microphonics "assessment " or a light finger-pressure feel .... The suspension health problem remains: there is no other practical way to determine the compliance of the  suspension for the common tech, much less audiophile.  At least with the stylus tip, you can use a microscope. Or ohm out the cartridge coils. 

About noisy (microphonics) ... yes, the suspension physically feels stiffer compared to other similar models I have. Also,  sonics are poor and lower in volume. 

So I suppose a drop in measured output (voltmeter) may be a way to make the issue academic. Still need a test record with known test patterns. 

So you can estimate compliance by "feel"?  The specific issue you cited in your OP is a common phenomenon not necessarily related to aging of the suspension and more related to the inherent microphonics of any cartridge.  The cartridge takes physical motions and converts them into an electrical signal.  So do microphonic vacuum tubes.  And so do microphones.  Hence the term. And speakers take an electrical signal and use it to make air vibrate in tune to the music in the signal. Speakers are microphones in reverse. I wouldn’t "feel" the suspension of any cartridge for too long or too vigorously.  That could damage it if it was not already subpar.
