Can you expand on why you would suggest someone should buy a used cartridge over a retipped cartridge?@big_greg
J.Carr explained it on this forum much better than me. But i will try again.
Just because you, me or anyone else have no idea about canculations made by the original cartridge designed for a certain high-end model - this is the reason why certain type of cantilever and stylus has been used (most of them are exclussively made for one particular brand and not available to anyone else, never ).
You can "upgrade" only cheap/average cartridges when you change one cantilever to another, or one stylus type to another. But your retipper can’t upgrade a state of the art high-end cartridge made by well knowd cartridge designers, just becase your retipped has no clue about many aspect of the original design, material and more important a calculation to match them together.
The right way to "retip" or "refurbish" a high-end cartridge is to send it to the original manufacturer and original designer who can work on it.
If you work on it with somebody else then you have no idea what you will get and it’s no longer an original cartridge. Maybe you will like it, maybe not, but this is not the original cartridge (cantilever, stylus mass, lengh, thickness can be way different compared to the original).
It’s funny when people are so concerned about cartridge alignment and micron difference between the protractors, vta or sra, but can accept a third-party cantilever or stylus instead of the original (sometimes unique) stylus/cantilever combo on their MC cartridges.
I don’t care what a honest retipper will tell me, i know that he does not have an access to the original materials available only to the original manufacturer. Also i’ve seen a pictures of retipped cartridges under microscope and compared them to the originals. The originals are way more accurate (or completely different).
And if we’re talking about just re-tip (on existing cantilever) then you will see the enormous amount of glue added by the retipper.
This is why i think it’s better to buy another cartridge NEW or LIGHTLY USED if the cost of the retip/refurbish by the original manufacturer is too much for a user.
So many great MC or MM cartridges available on the market for under $1k (new or used), this is why i think an OP could simply try another cartridge made by well known designer.
