Raul, I agree with you sort of, but not completely.
I have had many cartridges rebuilt by both the original mfr. and by third party retippers
Having the original mfr do the work preserves the value, and you get some additional assurance that it will be the same as original.
The OP has a no longer in production Lyra cartridge. If rebuilt by Lyra, it will still be worth far less than the original retail, and there is a value judgment to be made by the OP about whether he wants to pay a few thousand dollars for a rebuild.
The OP may want to, as you suggested, exchange it for a current model with Lyra giving a discount in exchange for his cartridge.
He needs to weigh all of the outcomes along with his pocketbook to make the best decision for himself. In my original post I suggested Lyra or a third party retipper.
In very few cases does the original mfr have some sort of secret sauce that allows them to refurbish the cartridge in a way that no other can replicate. My EMT JSD75s is an example that a third party could not properly replicate the result achieved by EMT. I had it rebuilt by EMT.
On the other hand my older out of production Shelter 901 I had rebuilt by a third party retipper and the results were great with the cartridge sounding as good as it ever did.
The OP bought a cartridge that sold for $6,000 new retail so I thought he could make his own value judgments about what to do with his cartridge.
Raul, you also have a great deal of experience and so can easily make the best decision for you. It seems appropriate that the OP be given the information he needs to make his decision and with all of this being said by you and I he probably has more than enough information.
Best Regards,
Jim Perry
