Grace F9 F8 F-9 F-8 Andante F9 F-9 H S Sumiko Pearl Supex Phono Stylus GAS Sleeping Beauty


According to most reports, Sumiko made both the F-8 and F-9. A good friend, who was a Supex, Audire, B&W and Theta rep back then, told me the F-9 was actually made by Supex, which would make sense, since Supex made all Grace moving coils. Also, I would imagine that Sumiko would have a stylus or two available if they made it. 

Sumiko imported these into the US, as well as Andante as a part of their line, and as a separate line for non-Sumiko dealers. FYI, The GAS Sleeping Beauty M/C was Supex 9E+, simply pressed into an an outer mounting shell. I use the Supex Mark IV (Timeline: E, E+, E+ Super, Mark IV are all the same, as far as my ears can tell. They just renamed it every few years.), which eventually morphed into Koetsu, and all of these are really great.

The Grace F9 came with different styli, the green E is elliptical with an alloy cantilever, and the the S is spherical. The red, top of the line is the Ruby, an elliptical with a ruby cantilever. There were both elliptical and line contact tips with a boron cantilever. There are even more F-9's, and all the same cartridge body and internals. 

For nearly complete info, check here, but some of the photos are wrong, i.e. a green cantilever holder on a non- F-9:

The original F-9 has a round shank, but a square one fits perfectly, because the inside has offset, rectangular shank, locating springs. I know, because I Have an E and sell an aftermarket S with the square shank. It sounds at least as good as the original S. Many of my customers say it sounds better, but I realize that this is simply because their 9 is worn out and this allows it to drag the bottom of the groove, giving both noise and poor contact pressure. 

All F-9 styli are interchangeable between either company's F-9. 

The Sumiko Pearl was also marketed by Grace as the F-8, and by Andante as the H or S with spherical styli. The Pearl and Black Pearl styli from Sumiko are a complete match and work very nicely.

The Sumiko styli do not work in the F-9 nor vice versa. I state this in my eBay ad, but some people are hard to convince. My stylus can be forced into the F-8 (According to the one customer who kept it, but had to order a second one after destroying the first, then he put this monstrosity up for sale on eBay.) I had a second one returned because he said it only put out on one channel. I am surprised it did that. The cantilever itself is a different length and the magnet does not align with the pickup in the cartridge body. I could modify it, but why bother, when Sumiko has good ones available.

I hope this helps. Dan Vignau

Hi Lew,

I've never seen a load capacitance recommendation for the Ruby, but FWIW the datasheet for the original F-9E lists "operating conditions," upon which the various specs are based, of loads of 80 pf and 100Kohms.  Presumably, though, those values were needed to support the specified bandwidth of 45 kHz, that was needed for quadraphonic reproduction, and would be less critical with regular LP's.

Happy holidays!  Best regards,

Thanks, Al.  I am surprised to learn of the 100K recommended load resistance. Perhaps this is part of the reason why my OEM Ruby sounded so great with my Silvaweld phono stage, where I installed 100K load resistors.  However, it sounds less great with other cartridges, which has me thinking of either installing a switch to select load R (= work) or fixing a 47K load (= less work).
Lewm,

Back in the day, I had a Sansui Quad system.  A QXR 7001.  That 100K load was to be use when playing those 4 channel records.  The 100K load setting was not needed nor used if you were using it to listen to 2 channel recordings. When playing these 4 channel records, you would switch in what was call a 4 channel demodulater which would load the cartridge with a 100K load.  The pre-amp was pre-set at the normal 47K so when listening to normal stereo 2 channel records, you would just not switch in the demodulater.  The 4 channel Shibata stylus would improve anything heard or recorded under the standard recording format of the day.  No requirement was ever stated that it had to be only used at 100K. To have done so would have only limited their sales and that is the last thing someone trying to sell something would want to do.
Regards,
Let’s get back to the Grace subject:
Any thoughts about GRACE F9 F (Descrete 4) cartridge ?
Is that the rarest of grace f9 series ?

According to the database Grace F9-F has the best specs and it’s top of the line Grace (with frequency response 10 - 60 000). Better than F9E and F9L (and all others, except maybe ruby).

The only missing info in this paper sheet is F9 RUBY for comparison.

So the F9F is one step behind Rury?

Seems like Grace F9-F rarely turns up for sale compared to any other grace 9' models. 






     I should have known to suspect the history of Grace as told to me by a factory sales rep for Supex. Oh Well, I have looked dumb before and it will certainly happen again. 
     I do stand by my assertion that there is exactly one Grace F-9. Only the stylus differs between models.
     Thanks for the corrections. I'll stay out of this until I learn more, except for this: My friend had a Black Widow arm with a GAS cartridge. It really looked like my Supex 900 in a "sheath" (As in OPPO and the Home Theater company that rewraps and renames when multiplying the price by 5 times), but I never actually saw them side by side.
