Real world life expectancy of a high end cartridge?
A literature review and survey of stylus life was published on The Vinyl Press in mid-2019. Lots of detail, research, etc., in an article entitled "The Finish Line for Your Phonograph Stylus…" Reasonable reference to keep at hand. Interestingly, c...

I wanted to add a comment on the controversy over so-called grey-market gear sellers, namely 2juki-cartridges on eBay and based in Hong Kong. Sorry to add to this thread on this topic, but nowhere else on Audigon is it as ripe as discussed here. E...

Real world life expectancy of a high end cartridge?
The analysis in the link below is most interesting. Empirical data and research is the best to get to the truth of matters. I have a partial bottle of Stylast but not used it in years; will start using what I have left.https://www.head-fi.org/thre... 
How do tell when my stylus is too much worn?
A poster in this thread mentioned Ortofon research on stylus wear pointing to a lifespan of 500 hours. I wanted to follow up on that since I have done some digging.A friend of mine reminded me about the Vinyl Engine (VE) forum library and its suit... 
How do tell when my stylus is too much worn?

How do tell when my stylus is too much worn?
@chakster, I have read that you believe these advanced tips may last longer than 500 hours. I’m fine with that, actually. I have not done the research necessary to say otherwise. I do agree with you that stylus life may be dependent upon shape, an... 
How do tell when my stylus is too much worn?
Dear @rauliruegas, Thank you for your post. And the heads up about Ortofon research. I may inquire again with them. You have been there before, and so have I and as reported in my essay, so have others. Even after I posted a link to my article, wh... 
How do tell when my stylus is too much worn?

This response is nine months late for poster aberyclark. You ask about differences in sound between the EX series and the Empress. Not exactly what you want but a detailed review of the Zx+ and the first iteration of the Empress is available o...

Which is REALLY the best Conrad Johnson Preamp
I know this thread is vintage now. But I’m curious how among the various C-J preamp/linestage options, how the PV15 LS stacks up. Also, CJ offers an upgrade in capacitors, so you can have a PV15, for example, upgraded with the Teflon caps they use...
