Grace Level ll


has anyone had any experience with these cartridges? Seem to be compatible with the earlier F8 cartridges, but with better cantilvers and stylus.

Can you provide more information? I've never heard of "Grace Level II". I own and enjoy a Grace Ruby. Thanks.
The cartridge line came out in the mid 80's. I believe it came out at the same time as the F14. The level 11 was based upon the F8 and the F14 was based upon the F9. They had upgraded parts, styluses etc. The one that I am looking at has a Boron Cantelever and a Microridge stylus. I am not sure if they had still offered the F8 or the F9 at the same time. I believe the F8 and F9 were from the 60's and 70's. The vinyl engine's cartridge base lists these cartridges and some of their specs, but I have not been able to find out a lot more about these. I believe most of these were offered in Japan and then Sumiko brought a few in. So they are rare cartridges. The seller is asking a comparable price to the Ruby. He considers the Level ll an upgrade from the F9. I am trying to see if anyone has heard one of these. I found 2 that sold in the past year, but have not got info from them.
Given the wonderfulness of my Ruby, I would be curious to listen to an F14. The nomenclature is still a bit confusing to me. There is "Level II" and within Level II there are F11 and F14? Is that correct? I've never heard of these cartridges maybe because I have not paid much attention to those very late Grace products. However, I do think the Ruby was made well into the 80s, at least. Correct me if I am wrong.

I have NOS (sealed) stylus for GRACE LEVEL II cartridge (Boron Cantilever and Micro Ridge tip). It was one of the most expensive model release in 1983 (the price was 37 000 Yen), this model was in production line untill 1988, more info here. I know it can be a huge upgrade for F8 cartridge and they must be compatible, it’s even better on the Level II of course. But is it compatible with F-9 and F14 ? I have F-9 and F14 as well, but since the Level II MR/BR stulus is still factory sealed i don’t want to experiment with them. Has anyone tried the Level II Boron/MicroRidge stylus on F-9 or F14 body?

I like Grace cartridges very much and F-9F (Shibata / Discrete-4) is the best one in F-9 series (imo), but the Level II and F-14 were the most advanced grace cartridges and that’s why they are so expensive and mega rare today.
Chakster, what you are looking for is listed on USAM. Just sayin'. 
Thanks for the info, but i will simplify my question:

F-8 LEVEL II and F-9 styli are not compatible ?
F-9 and F-14 styli are compatible ?

Anyone?
