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!

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.
The most compliant cartridge in the line is the Karat 17X which is 15 um/mN. That is medium. The DV 20X2 i2 12um/mN on the border. 
Koetsu's are very low at 5 um/mN. These are for use on a fork lift. Your favorite V15 is a high compliance cartridge 30 um/mN. Most people use these with a coat hanger.

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.
I'm using a 20+ year old Lyra Cclavis D.C.  The ONLY problem I ever had was a worn stylus.  Not worn out, just worn.  The stylus and cantilever were replaced a couple of years ago by Soundsmith.  I'm still satisfied with the cartridge.  I have a Lyra Skala that I intend to install one of these days.
I heard something recently about stylus longevity. My dealer said in passing that he was glad he sold me a Koetsu, because some clients had experienced excessive wear on some other expensive cartridges. This may be for any number of reasons, like not cleaning records, etc. But my experience with Koetsu is very good in this respect: minimal wear at 1000 hours.

I note also that Soundsmith puts their money behind their mouth with retipping. You could do worse.
