@lewm So why wouldn’t it be potentially beneficial to replace an elliptical with a line contact or some other more "modern" shape, in the process of re-tipping?
I want to hear and judge only original cartridges in perfect condition (from any manufacturer), if i need a better stylus or cantilever for my Gace MM i will do my best to find the original (NOS) with the best stylus/cantilever. I’ve had bad experience with refurbished mm cartridges, never again!
I do considering myself as a collector of genuine carts only, i will never buy any refurbished cartridge or any re-tipped cartridge when it comes to vintage carts of any type (MM or MC).
I often see how people are lying about condition of the cartridges they are selling on ebay, offering refurbished carts with aftermarket parts (completely different cantilevers or glued styli of the different shape and different mass) as the original. Someone even sold me refurbished carts as the original and never mentioned that they are refurbished. I just don’t want this experience anymore in my life. Re-tippers work or suspension repair does not looks nice under microscope compared to the original factory made genuine products. This is not for me.
In my opinion retipping/refurbishing service of some mega rare MM only make sense if there is no chance to find the original stylus replacement.
Refurbished vintage cartridge does not have any collectors value and the sound of such hybrid has nothing to do with the original sound. Some people see it as an upgrade, but i don’t see it like that. I believe that top quality vintage MM cartridges are superior to anything new and i am using only genuine carts so far. I would pay more for a NOS (sealed in the box) original than for refurbished cart from VdH or any other reputable master.
P.S. remember jp jones story about his Technics top of the line cartridge, the end of the story was pretty sad when someone tried to "refresh" the suspension of that rare cart. No one can guarantee the result of that job. This is not for me, never ever in my life i will send some rare working cartridge for some "fine tuning" or retip or whatever" to anyone.
