With this 'logic' one should probably not buy used records either. One never known how it has been handled, how often it was played and with what stylus, does one? Glad it isn't my logic, or else I wouldn't have any records.......
It has been said before, but bears repeating: what cartridges do you think those vintage records from the '50's and'60's were played with? We are debating on this forum whether sapphire is an acceptable cantilever material, but back in the day most people used a sapphire stylus! When the sound deteriorated it was worn and you simply flipped the stylus over to wear out the opposite one........
Yet most of these records have survived such crude devices, except in obvious cases of mishandling which are easy enough to see. The best of these are still considered the benchmark for sonic quality and many of them are worth more to collectors than the MC cartridges discussed here.
So why should you be so 'sensitive' about the condition of previously owned modern cartridges with a sophisticated diamond stylus?
