I use a Cartridge which was retipped from Soundsmith, too. Excellent result and it was not expensive.
Well done.
... This is our most economical rebuilding service. We employ an assembly comprising a ultra-light weight "Nude Elliptical" diamond for low moving mass, and an aluminum alloy cantilever. This represents what WAS found in most high quality cartridges in the past, and surprisingly, is often better than what is currently supplied as "original equipment" with new cartridges often costing over $1000.
Well done.
