Ceramics used in audio, sounds like a sexy idea, but every such implementation has been short-lived, so far. This suggests to me that it doesn't work very well. Kenwood made an optional ceramic mat for the L07D. They are VERY rare. I think they are rare because they did not sound as good as the standard stainless steel platter sheet and were unloved. But still sexy.
Chakster, When you wrote the above post on the 29th, did you know there is a Level II Grace for sale now on eBay, and that the seller is Russian? Asking price is way too high for a vintage cartridge that has unknown provenance and performance. I say this as a great admirer of the Grace Ruby, both with its original stylus and with an SS OCL re-tip. (I own both versions.)
