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.

Halcro - I have to agree with Raul, your numbers dont add up.

The MA-505s was no problem because it's overhang is the same as the FR-66s.....however the FR-64s has an overhang of 12mm as opposed to the 15mm for the others.
So to correct for that......I reset my P to S to 233mm for the 64s.
And yes......I know that the Av and Max distortion levels go up as a result.
The FR66 should be 12mm overhang not 15. The FR64 should be 15, not 12.
If you are running 12mm overhang on your FR64 then you should be moving the arm closer to the spindle to reduce distortion, not further away.

Dear Raul,
There are dozens of posts from you extolling the advantages of Lofgren A (Baerwald) over Stevenson, and your understanding of the distortions of each geometry is obviously flawed.
It just reinforces the fact that you can never be trusted or believed?
Oh.......and do I read it correctly?.....I was right about the 15mm overhang and you were wrong?
Nothing new about that..........

Dover,
Please see the VE Calculator Chart in my Post above.
Raul is not disputing the figure. His 0.3mm difference is due to his assumption of Stevensen geometry.
You've got it arse about :-)

Suteetat,
Yes....the UNI-Protractor is made and sold by Dertonarm who also has made a range of adjustable headshells which are receiving positive reviews....and has also just launched a new tonearm which debuted in the HighEnd Show at Munich.
Dertonarm (Daniel) knows more about the FR range of tonearms than anyone else I know.....unlike a Mexican peppercorn who has never owned an FR-66s....just look at his Systems Page where every tonearm he has owned is listed....incl the FR-64s?
This Mexican wannabe also was designing a new tonearm but where is it?
There are some people in Audio who have the knowledge and ability to design and produce.
Then there are the Pretenders who are full of hot air.
When the chips are down.....all they can do is....blow.

What is in a name? Well the name is about the reference
and when we want to find something we need a name. The
tonearm made by 'tonearm' (aka'Der Tonarm' in German) is
called the Axiom. The Arche headshell which we discussed
in the context of the 'iron horse versus locomotive' is included
or build in the Axiom. I got the Arche for free,
Thuchan got also the Arche for free but also the Axiom (?).
Some guys are more lucky than other.
