Larry, do you know the compliance of SoundSmith Ruby OCL ?
The original Grace is a high compliance cartridge, as stated by Raul the SoundSmith rebuild or just SoundSmith styli may be totally different from the original Grace specs (compliance for example).
I’m sure that SS Ruby with OCL is an upgrade for some of the F-9 models, but the luxury Level II (Boron/MicroRidge), F-12 (Beryllium Cantilever / Line Contact) and F-14 LC-OFC (Boron/MicroRidge) are amazing in stock condition. There was even Diamond Cantilever version of the Grace F-12 MM cartridge.
