Seeking arm suggestions for a Grace F9R


I recently bought an F9 body and a SoundSmith Ruby OCL stylus. I currently have it mounted on an Acos Lustre GST-801 with a 7gr headshell but still a bit heavy with the resonance is in the 7 hz range. I'm liking it's sound and contemplating changing arms. Any F9 owners willing to make suggestions of great matching arms for it. (no 12" please)
Thanks,
Robbie

Glad I checked in, sooner than my usual once a week. Silly me, to have trusted the Grace compliance figures, on the Vinyl Engine site. I’ve no doubt, their own manuals, would be the authority. VE doesn’t mention at what frequency their figures are given, nor- was I thinking about Japanese spec(Oldtimers Disease). And, like I said, I couldn’t swear to anything, regarding Mr Ledermann’s options, methods, materials, or end compliances, with his Grace rebuilds(in my reply to Mr chakster), so- thanks for that info, Mr dgarretson. I guess, now I can(except for whether the compliance is higher or lower). Happy listening, everyone! https://www.vinylengine.com/cartridge_database.php?m=Grace&t=any&mod=&sort=2&Search=...=
Mr chakster- The original Grace F9R’s compliance, was 12 x 10-6cm/Dyne(kinda medium compliance), as were the majority of the F9 series. Many of Mr Ledermann’s Soundsmiths, are in the 22 to 28 x 10-6cm/Dyne range. Don’t know if he can, does or will retip a Grace, with that kind of spec. Many retippers replace only the cantilever and stylus, reusing the compliance material. I doubt that he(Peter) reduces/lowers the compliance, though I can’t swear to anything.
According to the Vinyl Engine Resonance Evaluator, the 7G effective mass, of a Magnepan Untrac I, combined with your cart’s compliance/weight, will yield a 10Hz resonance. I’ve used both Denon 103D’s(same compliance as your Grace/1.5G more weight) and a Dynavector 17D3(just a tad lighter/slightly higher compliance), with excellent results. I own two of the Maggie arms(one since 1980). They are hard to find sometimes, but- well worth the search. They’re easy to set up and have all the pertinent adjustments. You may want to check with Mr Ledermann, as to whether your F9R still has the stock compliance.
