my conclusions come from my experience, my cartridges didn't sing after partial retip, but poeple need to get top hifi to hear the difference. I had to retip a benz LPS a few month ago, ALL retipping services answer me the same thing " we don't have microridge diamond + boron cantilever but ours diamond cut is much better, you will not hear the difference" that makes me laught. And some of them didn't even told me that they will mount a different cut, it's not serious at all. One time I had a used ZYX univers with a VDH diamond or zyx with shibata, but who cares, it's a diamond after all !!
@andychris Great post!
I feel the same about re-tipping and refurbishing, even after cartridge designers like J.Carr explained why it's a bad idea, some people still think that re-tippers in their garage are smarter than cartridge designers. We're in minority on this forum, the majority of people are happy about re-tipping with completely different diamonds/cantilevers. They are happy to pay extra money to convert clever design to some frankenstein, because re-tipper said it will be even better. One of the reason, in my opinion, is that only a few people can actually compare original sample to refurbished sample, in this case they must have both cartridges on hands, but after 5 month they can't even remember the sound of their ex original cartridge. And re-tipper will say that it must be better after burn-in (100 hrs). To my surprise many people are happy to deal with less known and less qualified re-tippers they are often advertise on this forum after the job is done. I think some audiophiles does not have enough cartridges, they want to stick to one or two and happy to re-tip them many times (instead of finding something new/better).
