I quickly became a cartridge collector and all my favorite vintage cartridges were purchased NOS (New Old Stock, some of them still sealed). It's not easy to find a NOS cartridge, but first we can try used and if we like it we will wait for a NOS to pay much more for it. This is how it works. We keep on moving, learning the process, searching for the best cartridges, we pay for mistakes, but in the end we got some amazing vintage cartridges in New Old Stock condition.
I definitely don't understand your style of buyin cartridges, except that you're looking for the most expensive ones. Some people strongly believes that each new cartridge must be played for 50-100 hrs to burn-in. Your $10k new cartridge may not be good enough if it was not used for 100 hrs.
Simple reason, you have no way of truly knowing how many hours that cartridge has on it. Plus, who knows how the rest of it is performing, suspension issues etc., Consequently , whether it is up to manufacturers specs is anybody’s guess.
Therefore, there are many folks, including myself,who aren’t going to risk what you propose; perhaps unlike you, they are not willing to risk damaging expensive vinyl with a once and done play due to the defective stylus.
You still don’t believe that these old worn vintage models and the worn out modern cartridge can be a factor in this regard. Remind me to never buy any vinyl from you, lol.
