retipping for Grado The Reference high output cartridge


Thinking about getting a retip done on my cartridge.  I know of someone in Brooklyn, NY and someone in West Hartford, CT and I believe Peter at SoundSmith might do this kind of work.  Any recommendations?

I didn't think Grado provided this type of service.  I'll check with them.  Thanks.

FYI, Grado does not provide retip service, but rather a trade in offer.  That would cost me $1,000, so not what I'm looking to do.   Thanks anyway.
