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

I've been using my F-14 LC-OFC with original L12B stylus on Victor UA-7045 with Stax HS-7 headshell. Another great arm for high compliance cartridges is stand alone Luxman TA-1 with arm stabilizer and removable armwand.  

But original Grace is high a compliance cartridge, SoundSmith refurbished is not a high compliance.

There are some nice original Grace styli with nude Shibata tip and nude LineContact tip, this models are the best in F-9 series, it was desidned for F-9F and F-9U (blue color). Upgraded version of FR-9U stylus was made for LEVEL II series (different plastic housing desing, but also blue color), i have two sealed NOS is anyone interested.

No, the majority of the Grace F-9 series are very high compliance cartridges, please look at the manuals first. The F-9F,F-9E, F-9U ... compliance is 25@100Hz and this is typical figure for Grace MM cartridges. Keep in mind that you have to multiply this figure on 1,5 at least to find out what is the compliance @10Hz

SoundSmith (as the US manufacturer) measuring compliance at 10Hz from the start, so this is correct. But all japanese manufacturers measure compliance at 100Hz and this is whay different from the reality, so it must be converted. However, 25@100Hz is already high, it reality it’s about 40@10Hz (very high compliance).

I don’t think the original F-9 Ruby is lower in compliance compared to all the Grace F-9. The only low compliance grace F-9 is F-9P (Professional), this figure is 10@100Hz (about 17@10Hz)
This is how it looks with SoundSmith brand new stylus assembly.

This is the Grace F-9F with nude Shibata stylus (RS-9F first generation rounded shape). It my old picture, not i have second generation of the FR-9U Level II styli (Line Contact).

here is a picture from the internet of the secong generation grace Ruby stylus (not rounded shape as the first generation). But the stylus is on ALL original Ruby is Elliptical: http://photos.imageevent.com/puma_cat/fujif31andf20photos/Grace-2.jpg




@keemoment 

But one should note that over in discussions at VE, someone there had an image of he original stylus having a resistor (?) inside the brass barrel and that it accounted for the MC-like quality of the F9E.

It's called tension wire, not a resistor

@keemoment Then please add a link to the forum or a link to the picture. I don't have F9, but this is bras shank of my F12 and it's better made stylus replacement than F9. There is a brass nut to protect tension wire, but on F9 there is a drop of glue to fix tension wire.
