no, the cantilever is often stressed in the retip and the seating in the cartridge can be damaged by the heating necessary to do the retip. Starting new is the best and most cost effective way. Think about it, Shure used a completely removal cantilever assembly to great advantage.
does a stylus retip makea cartridge as good as new
I notice quite a few cartridges being offered on Agon with stylus retips and claims that the cartridge is as good as new- or better! I thought cartridges deteriorated with age due to oxidation regardless of tip wear. I seem to remember Michael Fremer in Stereophile giving a life of about 5 years. Am I wrong?
