Teach me about cartridge 'retipping'

Dear @needlestein : I'm not an expert of cartridges as you and other re-tippers or even audiophiles but maybe when @jcarr posted on that issue he was refering to tyny changes on the cartridge motor or in compliance, I don't know but maybe he can clarify about because through the years @jcarr always made precise/true explanations on different audio issues.

I’m sure he was, but if you aren’t messing with the suspension or the cartridge motor, it makes no difference.  If you are messing with the suspension and the motor, then you aren’t retipping. You are rebuilding.  In that case, then, yes, lots of things can happen that would affect sound and operation.

Exactly an that’s the main subject on what I posted about that came from JC and that's a very high advantage for the top Lyra model owner because he will receive his cartridge with the latest up-date that no re-tipper can does because not even know what the cartridge designer made it, it is a " propietary " up-date.

One of the drawbacks of the Lyra design is that it lends itself easily to repair.  

 That made me laugh ;).

I think its worth saying again: skill in building the transducer and a well organized parts grading system are what elevates the best cartridges. The same boron cantilever can easily be found on $1k carts and $10k carts. That does not mean the carts are the same.
I also think it is worth repeating: thank goodness we have so many good cartridge repair options! The darn things do break after all :)

Are you convinced by this argument?  Lyra doesn’t even retip their own cartridges anymore from what I understand.  So the point is moot.  I’m guessing the only “proprietary” updates that would really be happening at the retip level and not the rebuild level would include something like the installation of Lyra’s exclusive 3/70 Ogura Vital stone.  Or maybe someone would send in a model with a Namiki Micro Ridge like an old Delos.  Lyra doesn’t use the Micro Ridge anymore, so the proprietary update would be, what exactly?  A different stone anyway?  I can play that game, too.  Want a Lyra, but you’d really rather have a Fritz Gyger FG2 on it or maybe even an FG S?  Send it to me.  I’ll take care of you.  Want a 2.5/75 Ogura that is 0.5 micron finer on the tracing edge and 5 microns longer on the scanning edge than a standard Lyra?  Send it to me.  I’ll take care of you.  
Guys who hot rod cars and motorcycles don’t fall for these arguments to only use genuine replacement parts in their projects.  That’s the fun of hot rodding.  These manufacturer arguments that hot rodding is always bad practice are pretty thin, don’t you think?  What if you want a sapphire cantilever?  You seriously aren’t going to do it because Jonathan says not to?  I have personal insider information that Jonathan likes rebodied and retipped Denon DL-103s.  So he doesn’t take his own advice.
