What is the average lifespan of a phono cartridge?

Hah Lyras have whole different story on longetivity. 2nd to none indeed.

My findings are similar to others as posted. I had 2 Benz Ruby 2s which lasted for about 4-5 years. I am now using a Transfiguration Orpheus which is 3 years old and still very good. I'm not sure you can wear out a diamond stylus if your cart/arm are set up optimally. With commonly available anti-skate adjustability and digital scales enabling users to fine tune dynamic tracking force, I think in general cartridges are lasting longer than they did 20 years ago. I have been led to believe that the first thing to go is the suspension and not the stylus. Mistracking can often be heard on the inner grooves of poorly pressed or poorly cared for commercial pressings. I have found little or no distortion on the inner grooves of audiophile pressings even after the cartridge has been deemed old or worn out.

This is a great question. I began buying classic used cartridges ten years ago when a new cartridge I just bought disintegrated as I was installing it. It just fell apart, the body from the mount and the stylus assembly. I always wanted a Koetsu Pro IV, at the time they were unavailable new so I took a chance on a used one. It was perfect, so I bought another one six months later and it worked great. Since then I've bought (and sold to try others) over 20 second hand "classic" cartridges and all performed fine. Go figure. I suspect people who trade cartridges are just trying something new and thus don't put many hours on them.

I have bought in 1998 a second hand mk levinson mlc-1, it has been retiped twice by Van den Hull since that date and it works quite well. When you send it for retiping the company can have a look at the rubber suspension part and change it. I use it around 4 hours a week on a big plinthed lenco with a OL conqueror mk II and am quite satisfied.

I thought people might be interested to know that my Rondo Red has just passed the 2,000 hour mark and is showing no signs of deterioration. The cartridge was initially aligned using a Mobile Fidelity Geo-Disc.

I traded the last Rondo Red in well before the 2,000 hours, which I now slightly regret, but this time I thought I'd see just how long it would actually last. I have a new Quintet Black S ready for when this happens.

All records, new or preowned, are vacuum cleaned and transferred to anti static sleeves prior to the initial play. I use a carbon/felt brush for the discs and a carbon brush for the stylus before and after each side.

No other treatments are applied.

Hope this information is helpful.
