You can buy modern replacement styli for vintage cartridges that use modern synthetic rubbers that will last for decades out side. Styli back from the day are probably bad by now. Not only that but quality control was pretty poor back then.
@mijostin you can’t buy modern replacement for most of the best MM cartridges from the past because those type of cantilevers are NOT available anymore. But NOS originals are still available (but rare). If all post about weakness of rubber is nothing buy a fantasy, I have practically tested so many vintage MM (the best ones, not crap).
Instead you’re talking about rubber parts, do you think it’s more important ?
After years of contributing on this forum I have posted thousands of pictures and articles, but people like you ignoring everything and continue to post nonsense.
-Ever heard about Boron PIPE or Beryllium PIPE cantilevers ?
-Ever tried a ceramic cantilevers (also pipe) ?
-Sapphire or Ruby that are completely different from what SoundSmith can offer today ?
-Gold-Plated Beryllium maybe?
-Even aluminum cantilevers from Japan is not what you can buy today.
You will never find any of those great exotic cantilevers today, no matter how much you can pay, even on $20 000 MC you will never find a Beryllium anymore (production of this material was restricted long time ago), no more Boron Pipe (too expensive to made) ...
Quality control was MUCH higher and those cartridges made in JAPAN !
This country was way ahead of USA or Europe in technology.
This is the reason why the best MM are from JAPAN and they are extraordinary good even today because of the quality control and very high competition between the giants of the industry.
Even cartridge design (visually) was much better than all those ugly looking modern cartridges. Headshell integrated carts like this one is superior design and engineering. I can't post all of them here now, but there are so many amazing cartridges made in analog era, not in digital era.
