Question on FR 66s


For some reason, search on FR 66s in agon did not turn up anything much. I recalled that recommended S2P distance is 296mm rather than 295mm and Stevenson geometry seems to work best. Is this correct? I already have FR 64s which works very nicely with Koetsu. In general, does FR 66s works well with the more modern cartridges, Lyra, Air Tight, Dynavector etc.
I am kind of curious to try it but not sure what to try it with. Beside those mentioned on my system page, I have Kiseki Blue, XV-1s and Miyajima Zero on hand currently.

Thanks for any suggestion.

Dear Nandric, adding the cost of headshells and Oyaide silver leads, soon FR 64s seems like a bargain :)
Dear Suteetat, The FR-64 s was a bargain in the 80 is and still is. Your choice of the headshell however should be dependant from the cart you use or intend to use. By changing the headshell you also change the eff. mass of the arm. So there is no headshell to be known a priori.
Halcro, one of the reasons why the Graham has been highly touted is it is a well built unipivot and has a tremendous speed and transient response. Did you miss any of that in the FR64s ?
Pain,
I've had four unipivots.......Hadcock GH-228, Grace 940G, Continuum Copperhead and Phantom II.
I never found the Graham to be better in its speed or transient response than any of the other unipivots.
I can say that the FR-64s and 66s better the Graham in all meaningful parameters in my system.
As for build quality..........the FR arms as well as arms by the Japanese masters like Micro Seiki, and SAEC are simply in a different league to the Grahams........or any other modern arms I know of?
Thanks Halcro.
At present I use two unipivots, Naim ARO and 47 Labs RS-A1. Both are very fast and open sounding tonearms. I will now try out a FR64s and possibly report back on this same thread.
