Cartridge reliability


Not having purchased a cartridge in at least 15 years, and probably more, I’m curious what has been your recent experience with cartridge reliability. Any cartridge failures? Significant channel imbalance? Loss of a channel? Suspension collapse? Etc. My focus is on moving coil cartridges.

I’m trying to get an idea of which manufacturers are tops in terms of reliability/QC and which have a thing or two to yet learn. I’m asking as my cartridge, though still sounding quite nice, surely can’t last forever. 
For instance, I’ve read about some albeit quite rare problems with Lyra, but I can’t recall ever hearing about any Dynavector issues. I have heard of some issues with Goldring 

your own user experience is appreciated!

thanks!

Do you think your next cartridge must be your last cartridge?
Why? 

With advanced stylus profile like MR you can use a brand new cartridge for 2000 hrs according to the manufacturer. It's too much time if you're not playing records everyday.  

Then you can just buy something else. Do not try to find an MC cartridge that will last forever, especially those new MC. 

If you're so concerned about stylus wear or suspension condition then buy an MM cartridge and spare styli - this is the best you can do. 

Did you every try a good MM or MI ? If you want something user friendly then look for a cartridge with user replaceable stylus, but get the best MM/MI if you want superb quality.  

P.S. I want to correct a previous poster, Dynavector are NOT for heavy tonearms. Actually, Dynavector LOMC cartridges are high-ish compliance, they are great (Karat series for example) for mid mass tonearms. 


Excuse me chakster. The top 4 cartridges in the Dynavetor line have a compliance of 10 um/mN. That is most definitely at the low end of the scale. Better with heavier arms.

It’s a common mistake @mijostyn

Japanese manufacturers measure dynamic compliance at 100Hz, not 10Hz as you expect!

Dynavector is not a low compliance cartridge, to convert compliance from 100Hz (Japanese system) to 10Hz you have to multiply it on 1.7 at least.

It’s been discussed before on another forum:

"On to the information contained in the response from Dynavector, 100 Hz is not the normal 10 Hz used for compliance testing and there are notations about this on the cartridge database indicating that the compliance might be as much as twice as high at the normal 10 Hz test frequency."

I own Dynavector cartridges.
What I have now is 17D2 mkII (dynamic compliance 15 @ 100Hz)

BUT at 10Hz it’s nearly 26 cu and this is definitely not a low compliance, you know that Grado MI is 30cu and it’s high compliance.

For this reason you can see Dynavector KARAT on Well Tempered Lab tonearms.

@zavato

V15’s and Infinity black widows

Not the best cartridge and average lightmass tonearm (fragile).

Denon DA-401 tonearm is much better, as for the cartridges you can try low impedance (low output) MM like Pickering XLZ-7500 designed for MC phono stage (or MM phono stage with high gain), or even with SUT or Headamp. Spectacular cartridge with user replaceable Stereohedron stylus, the best model (top of the line, expensive). Low impedance MM are unique. Expert stylus in UK can service them.

Regarding some very nice MM look for SONY XL-50 with Boron Pipe cantilever, this is a high compliance cartridge. Jico replacement available for this model, but original is superior.
Chakster, how do you know that any manufacturer’s compliance rating is at 10 or 100 Hz. It usually does not say. Certainly the math is done at 10 Hz RF = 159 divided by the square root of Mass X Compliance. So it makes more sense to report it at 10 Hz. You assume that just because a cartridge comes from Japan that it is automatically reported at 100 Hz.


Yes, and basically this all you need to know. You will never find a Japanese cartridge designer who will use 10Hz, maybe there are an exception, but 99,9% of the Japanese designers always use 100Hz.

Keep it as a cultural thing, it’s JAPAN, not USA




I do not own a Dynavector.

I owned 3 different Dynavector LOMC and over 60 different Japanese cartridges (new and old) of all types. So I have some personal experience.




Moving magnet cartridges tend to be more compliant than moving coil cartridges because their moving mass tends to be lower. I have an Audio Technica VM95ML It’s compliance is listed as 7 um/mH at 100Hz. That would make it 14 um/mN at 10 Hz. This AT is less compliant than the Dynavector?


Some MM (MP) carts like Nagaoka are low compliance, cheap Ortofon Concorde and OM are also very low compliance cartridges and they are MM.

Yes. Dynavector KARAT is higher compliance than some modern MM.


Obviously it would help if the manufacturers would specify specifically how the compliance was measured.

All manufacturers (except for Japanese) are using 10Hz to measure Dynamic compliance (All American and European manufacturers).

Japan is always 100Hz, this is rule №1

Dynavector compliance is just like ZYX (12-15cu @ 100Hz). And when I asked ZYX via US distributor it was confirmed. They think it’s not good to measure a cartridge using 10Hz, so they are using 100Hz instead for safety reason! It was like a quest for me 7 years ago to figure out how and why it's 100Hz and how to convert it back to 10Hz.
