So, you've answered your own question.  If you're satisfied with the story that goes along with any used cartridge, then buy it.  Worst case scenario, if you're not happy, is you can change to a sapphire cantilever + LC stylus per the services of Soundsmith.  I did that with my OEM Grace Ruby, and I found it to be a major upgrade.

Well, thank you, I will think it over ....I have such excellent cartridges with original needles as Victor x-1/II, pioneer pc-600,  shure V-15III, AT 150MLC, sony XL-45, all MM, and only one but very excellent victor mc-5E (MC),

I wonder is Grace F9 U at the same level, and will I hear more wor different of what I hear already with what I have?

Is Your Ruby Grace F9 your best cartridge and what you compare it with?

Completely agree with lewm. I bought a NOS, new in box F9e a few years ago. The Soundsmith replacement stylus was an obvious upgrade even from an used stock stylus.

You name six different cartridges, none of which is "bad", and ask whether the Grace will stand up to them in SQ.  I only know one person who may own all or most of the cartridges you already own, and that is Raul.  So maybe Raul can offer his opinion.  But even Raul can only offer an opinion based on his system and listening acumen, which is considerable.  In the end, you have to decide.  In my partially informed opinion, the Grace has a place in that group.

No, the Grace Ruby, even with the SS upgrade, is not my best cartridge.  It's probably my favorite MM, but I own two MI types and at least one LOMC type that I would rate ahead of it, but we're talking about lofty regions of excellence.  I really don't think in these terms.  The Ruby/SS is among the 6-7 cartridges that I use, while maybe 15 others sit in a drawer.
