I have really been pleased with the 8 carts that I have had rebuilt by Soundsmith
It a destiny of MCs
Personally i don't think it's normal that so many nice (sometimes unique and exotic cartridges) from many different manufacturers/designers are all goes to one person for refurbishing with third-party parts.
This is one of the reason i love the MM cartridges, at least we can change the cantilever/stylus assembly by ourself in 5 seconds (if we have original replacement) without ruining the sound character of the cartridge. No compromises here.
Refurbished some special MC cartridges by third-party vendor is always a compromise. Good business for the vendors, but is that good for the cartridge?
Someone should make a direct comparison of those unique cartridges in stock condition to the refurbished cartridges with different parts (cantilever, stylus).
Our memories, unfortunately, can not hold the information of particular sound for a month, comparing refurbished cartridge to the memories is not a good idea. We're always biased by the new toys. We have to compare original to refurbished in the real life in the same system.
